The Basics of Techum Shabbos

Question #1: Camping sisters

“My sister’s family and ours are each spending Shavuos at nearby campsites. We were told that we could get together at a third spot between our two places for a Yom Tov barbecue. If we return on Yom Tov with the leftovers, must we keep track of who brought which food?”

Question #2: Bungalow bar mitzvah

“A friend is making a bar mitzvah in a nearby bungalow colony. How can I find out if his colony is within my techum Shabbos?”

Question #3: Eruv Techumin

“A lecturer will be speaking in the mountains not far from where I will be spending Shabbos. I was told that he will be just a bit beyond my techum Shabbos. Is there a way that I can go to hear him?”

Introduction:

In this week’s parsha, the Torah recounts the story of the manna, also including the unbecoming episode where some people attempted to gather it on Shabbos. In the words of the Torah:

And Moshe said, “Eat it (the manna that remained from Friday) today, for today is Shabbos to Hashem. Today you will not find it (the manna) in the field. Six days you shall gather it, and the seventh day is Shabbos – There will be none.”

And it was on the seventh day. Some of the people went out to gather, and they did not find any.

And Hashem said to Moshe: “For how long will you refuse to observe My commandments and My teachings? See, Hashem gave you the Shabbos. For this reason, He provides you with a two-day supply of bread on the sixth day. Each person should remain where he is — no man should leave his place on the seventh day” (Shemos 16:25-29).

Staying in place

Although someone might interpret the words, Each person should remain where he is — no man should leave his place on the seventh day to mean that it is forbidden even to leave one’s home, this is not what the Torah intends. According to Rabbi Akiva (Shabbos 153b; Sotah 27b; Sanhedrin 66a), the Torah, here, is indeed prohibiting walking beyond your “place” on Shabbos, but this proscription prohibits walking only more than 2000 amos (approximately half to two-thirds of a mile*) beyond the “locale” where you are spending Shabbos. This border beyond which it is forbidden to walk is called techum Shabbos, quite literally, the Shabbos boundary. How do we determine where this boundary is, beyond which I may not walk on Shabbos?

There are some basic factors that determine the extent and boundaries of one’s techum Shabbos. The first is whether you are spending Shabbos within a residential area or not. I am going to present several options which will help explain how to determine someone’s techum Shabbos.

Our first case is someone spending Shabbos in a typical city, town or village where the houses are reasonably close together, meaning that the distance between the houses is 70 2/3 amos (about 105-120 feet*) or less. In this instance, one’s techum Shabbos is established by measuring the 2000 amos from the end of the city, town or village. The “end” of the city is determined, not by its municipal borders, but by where the houses are no longer within 70 2/3 amos of one another.

When two towns or cities are near one another, halachah will usually treat the two towns as one, provided that the houses of the two towns are within 141 1/3 amos of one another (Mishnah, Eruvin 57a). This is twice the distance of the 70 2/3 amos mentioned above. The details of the rules when and whether one combines two cities for determining techum Shabbos purposes will be left for another time.

Techum Shabbos in a bungalow colony

Until now, we have discussed the techum Shabbos of someone spending Shabbos in a city. How far is the techum Shabbos of someone spending Shabbos in a resort hotel, side-of-the-road motel, or bungalow colony?

One spending Shabbos in a bungalow colony will have a techum that is at least 2000 amos beyond the last house of the colony. If there are other houses or bungalows within 70 2/3 amos of the residences of your colony, those houses or bungalows are included within your “place.” Under certain circumstances (beyond the scope of this article), they can be included within your “place” even if the houses or bungalows are within 141 1/3 amos of one another.

If the house, hotel or motel in which one is spending Shabbos is outside a city and more than 70 2/3 amos from any other residential building, one measures the techum Shabbos from the external walls of the house.

Shabbos while hiking

Someone spending Shabbos in an open field is entitled to four amos (between 6 – 7.5 feet*) as his “place,” and the 2000 amos are measured from beyond these four amos.

Proper placement

We have now established that the definition of one’s “place” for techum Shabbos purposes depends substantively on whether one’s residence for Shabbos is indoors and on whether there are other residences nearby. We will now learn that although techum Shabbos is a boundary of 2000 amos, one usually has a greater distance in which one may walk. This is because techum Shabbos is always measured as a rectangular or square area. We take the four points that are the easternmost, the southernmost, the westernmost and the northernmost points of your “place,” and then draw an imaginery straight line that begins at 2000 amos beyond each of these points. In other words, we will measure 2000 amos east of the easternmost point and draw an imaginery north-south line at that point. We will similarly measure 2000 amos north of the northernmost point and draw there an imaginery east-west line. We repeat this for the other two directions of the compass. The result is a rectangle (or perhaps a square) whose four closest points are each 2000 amos distant from your “place.” Obviously, this means that the techum Shabbos area is significantly larger than 2000 amos beyond one’s “place.” This establishes the techum within which one is permitted to travel on Shabbos. By the way, all the rules of the laws of techum apply on Yom Tov.

Property placement

One of the interesting, and lesser-known, details of the laws of techum Shabbos is that possessions is also bound by the laws of techum Shabbos. This means that my possessions cannot be transported on Shabbos beyond the area in which I myself can walk. This halachah is not usually germane to the laws of Shabbos, since, in any instance, it is forbidden to carry on Shabbos outside of an enclosed area. The halachah is therefore more germane on Yom Tov, when one is permitted to carry. For this reason, the discussion of these laws is in mesechta Beitzah, whose subject matter is the laws of Yom Tov. This subject is one of the main points of the fifth chapter of the mesechta.

Camping sisters

At this point, we can discuss our opening question: “My sister’s family and ours are each spending Shavuos at nearby campsites. We were told that we could get together at a third spot between our two places for a Yom Tov barbecue. If we return on Yom Tov with the leftovers, must we keep track of who brought which food?”

These two families are spending Yom Tov in locations where they have different techumin, yet they are close enough that there is some overlapping area located within both of their techumin. Each family may walk on Yom Tov to this overlapping area, carrying the items necessary for the barbecue. Everyone must be careful not to walk beyond the area of his own techum. In addition, since the items used for the barbecue were owned by one or the other of the families when Yom Tov started, each item may not be removed beyond its owner’s techum until Yom Tov is over. Thus, if one sister brought the hotdogs or the paper plates, the other sister may not take those items back with her, if she will be removing them to a place beyond her sister’s techum.

Min hatorah or miderabbanan?

The rules of techumin that I have so far presented are held universally. However, there is a major dispute whether these rules are min hatorah or miderabbanan. There are three basic opinions. The tanna Rabbi Akiva, mentioned above, rules that the Torah forbade walking on Shabbos more than 2000 amos from one’s place, as we previously defined it. The Sages who disagreed with Rabbi Akiva contend that the prohibition of traveling 2000 amos is only miderabbanan. (Whether Rabbi Akiva held that techumin on Yom Tov [as opposed to Shabbos] are prohibited min hatorah or only miderabbanan is a dispute among rishonim; see Rashi, Tosafos, and Turei Even, Chagigah 17b.) However, there is a further dispute whether the Sages contend that there is no prohibition of techumin min hatorah at all, and the prohibition is always only miderabbanan, or whether the basis for the prohibition is min hatorah. According to the Talmud Yerushalmi (Eruvin 3:4), traveling more than 12 mil, which is the equivalent of 24,000 amos (approximately 6 – 8.5 miles*), is prohibited min hatorah. This last position is quoted by the Rif (end of the first chapter of Eruvin). Several rishonim rule according to this Yerushalmi (Rambam, Hilchos Shabbos 27:1 and Sefer Hamitzvos, Lo Saaseh #321; Semag (Lo Saaseh 36); Sefer Hachinuch, Mitzvah #24). On the other hand, many rishonim (e.g., Baal Hamaor, Milchemes Hashem, and Rosh, all at the end of the first chapter of Eruvin; Ramban’s notes to Sefer Hamitzvos, Lo Saaseh #321; Tosafos, Chagigah 17b s.v. Dichsiv) contend that the Bavli disagrees with this Yerushalmi and holds that the concept of techum Shabbos is completely miderabbanan, and that the halachah follows the Bavli, as it usually does.

A nice-sized place

Six miles sounds like a distance considerably more than I would walk on a Shabbos. From where did the Yerushalmi get this measurement?

The basis for this distance is the encampment of the Bnei Yisrael while in the Desert, which occupied an area that was 12 mil by 12 mil. Thus, when the Torah told each Israelite not to leave his “place,” it prohibited walking outside an area this size (Tosafos, Chagigah 17b s.v. Dichsiv). According to the Talmud Yerushalmi, no matter when and where one is spending Shabbos, one draws a square or rectangle 12 mil by 12 mil around one’s city, colony or campground and this area is considered your “place.” Beyond this area, the Torah prohibited you to walk, according to the Yerushalmi.

Although it is anyway prohibited to walk beyond one’s 2000 amos techum on Shabbos and Yom Tov because of the rabbinic ruling of techumin, there are some practical instances where the question of whether there is a Torah-forbidden techum of 12 mil becomes germane. For example, the Gemara (Eruvin 43a) discusses whether the prohibition of techumin applies when one is more than ten tefachim above ground level, called yesh techumin lemaalah miyud or ein techumin lemaalah miyud. An example of this case, quoted by the poskim, is a situation in which someone wants to walk quite a distance on Shabbos atop narrow stands or poles that are all more than ten tefachim above ground. If one rules that there is no law of techumin above ten tefachim, ein techumin lemaalah miyud, then it is permitted to travel this way on Shabbos, no matter how far one travels. On the other hand, if there is a law of techumin above ten tefachim, it is prohibited to travel this way.

This question is raised by the Gemara, which does not reach a definite conclusion (Eruvin 43a). Both the Shulchan Aruch and the Rema (Orach Chayim 404:1) rule that one may travel lemaalah miyud for a distance greater than 2000 amos, because one may be lenient in a doubt regarding the rabbinic prohibition of techum shabbos. However, since traveling 12 mil is prohibited min hatorah according to those authorities who rule like the Yerushalmi, one should be stringent not to travel lemaalah miyud for a distance of 12 mil or farther. The Gra, however, rules that one may disregard the opinion of the Yerushalmi and the ruling of the Rambam, because the halachah follows the Bavli that there is no prohibition of techum at all min hatorah. Since the prohibition of techumin is always miderabbanan, one may be lenient to rule that ein techumin lamaaleh miyud. There could be contemporary applications if someone ended up on an airplane when Shabbos begins (for example, because of a life-threatening emergency), whether he is permitted, upon landing, to leave the airport terminal before Shabbos ends.

How do we rule?

Regarding the dispute between Rabbi Akiva and the Sages whether the requirement of remaining within a techum of 2000 amos is min hatorah or miderabbanan, it is universally accepted that we follow the opinion of the Sages that techum Shabbos of 2000 amos is miderabbanan. A result of this ruling is that if someone needs to use comfort facilities and there are none available within his techum, he is permitted to leave his techum for this purpose, because of the rule that kovod haberiyos, human dignity, supersedes a rabbinic prohibition (Berachos 19b).

Moving my techum Shabbos

“A lecturer will be speaking in the mountains not far from where I will be spending Shabbos. I was told that he will be just a bit beyond my techum Shabbos. Is there a way that I can go to hear him?”

The answer is that one certainly can, by creating an eruv techumin. This halachic entity allows me to move the “place” from where we measure the techum Shabbos. Ordinarily, my techum Shabbos is measured from where I am when Shabbos starts. However, when I make an eruv techumin, I move my “place” to the location of the eruv. If my eruv is placed such that both locations — where I am when Shabbos begins and where the speech will be delivered — are within its techum Shabbos, I may go hear the speaker.

But be careful. Creating an eruv techumin is not only a leniency, it also creates a stringency. Since I cannot be in two different “places,” if I use an eruv techumin, I have moved my techum Shabbos, not expanded it. Although I gain in the new direction, I lose the full techum I would have had in my actual location.

In this way, eruv techumin is different from the other two types of eruvin, eruv tavshillin made when Yom Tov falls on Friday, and eruv chatzeiros, which is made so that I can carry between two adjacent, enclosed properties that are owned by different people. The other two eruvin create leniencies but carry with them no attached stringencies. For this reason, the other two eruvin can be made for someone who does not know that the eruv is being made, since it provides him with benefits and no liabilities. However, since an eruv techumin includes liabilities, one cannot make an eruv techumin for someone who does not want it or who does not know about it (Mishnah, Eruvin 81; Shulchan Aruch, Orach Chayim 414:1).

Only for a mitzvah

There is another major difference between eruv techumin and the other two types of eruvin. One may use an eruv techumin only if there is a mitzvah reason to walk where it would otherwise be outside one’s techum (Eruvin 31a, 82a; Shulchan Aruch, Orach Chayim 415:1). For example, someone who wants to hear a shiur or attend a sheva brachos may use an eruv techumin to do so. But one may not use an eruv techumin to attend a social gathering, where no mitzvah is accomplished (see Mishnah Berurah 415:5). On the other hand, one may make and use either an eruv tavshillin or an eruv chatzeiros even if there is no mitzvah reason to do so.

How do I make an eruv techumin?

To make an eruv techumin, one puts some food before Shabbos where you want your “place” for Shabbos to be. There must be enough food there so that each person who wants to use the eruv techumin could eat two meals. If one used a condiment for an eruv, one needs to have enough so that each person who wants to use the eruv would have enough condiment for two meals. One recites a brocha asher kideshanu bemitzvosav vetzivanu al mitzvas eruv, and then makes a declaration that this is his eruv to permit him to walk in this direction.

Since this food will basically be left exposed to the elements and animals, many people use a bucket of saltwater, which qualifies as an eruv techumin. Note that saltwater does not qualify for the other two types of eruv, eruv chatzeiros and eruv tavshillin.

Because there are many complicated laws about eruvin that are beyond the scope of this article, I suggest that someone who needs an eruv techumin consult with his rav or posek.

Who instituted eruv techumin?

The Gemara teaches that Shlomoh Hamelech instituted eruvin (Eruvin 21b). We find a dispute as to which type of eruv the Gemara is referring to. Rav Hai Gaon (Teshuvos Hageonim #44) explains that Shlomoh Hamelech instituted eruv techumin, whereas Rashi (Eruvin 21b) and the Rambam (Hilchos Eruvin 1:2) explain that he instituted eruv chatzeiros.

Conclusion

The Gemara teaches that the rabbinic laws are dearer to Hashem than the Torah laws. In this context, we can explain these mitzvos, created by Chazal to guarantee that the Jewish people remember the message of Shabbos.

Do People Live in the Zoo, Part II

PENTACON DIGITAL CAMERALast week, I raised the following questions:

Question #1: Checking inside the eruv

“Can the eruv fences, walls, and wires be checked religiously every week, yet the eruv is invalid?”

Question #2: Shabbos in a warehouse

“May one carry in a warehouse on Shabbos?”

Question #3: Do people live in the zoo?

What do the previous two questions have to do with the title of this article?

One may carry inside such an area only when it is no larger than 5000 square amos (Mishnah Eruvin 23a), which equals approximately 1000* square meters or 10,000-11,000 square feet. For the balance of this article, I will refer to an area larger than a beis sasayim, that is, one that contains more than 5000 square amos, as a large area, and any area smaller than this as a small area. There is another factor that must be met to permit carrying in a small area that is not enclosed for residential use – its length may not exceed twice its width by more than one amoh (Mishnah, Eruvin 23a).

We will now continue our topic from where we left it last week.

Water sources

If a body of water, such as a lake or stream, is within an enclosed area, is the area still considered mukaf ledirah? Similarly, if an area was mukaf ledirah and then became flooded, may one still carry there (Eruvin 24a-b)?

On the one hand, since people do not live under water one could argue that any area covered by water is, by definition, not suitable for human habitation. On the other hand, mankind cannot survive without water; a nearby source of potable water is definitely a residential need.

The halachah is that water covering the ground does not usually create a problem, but there are three factors to be considered:

The quality of the water – can people use it?

How large an area is covered by water?

How deep is the water?

If the water is deep, not usable and covers a large area (more than 2500 square amos), that area is not mukaf ledirah, and the enclosures surrounding it do not permit one to carry there.

How deep?

According to most authorities, one need be concerned only when the water is ten tefachim deep, which is about 80 centimeters or about 2.5 feet (Shulchan Aruch, Orach Chayim 358:11). Others are more stringent and are concerned when the water is only three tefachim deep (quoted in Biur Halachah ad loc.).

Water quality

What is meant when we say that the water is usable? This issue is a subject of dispute among both early and late halachic authorities. There are two basic approaches, a stricter approach, which defines usable water as being drinkable (Rashi, Eruvin 24b s.v. Dechazi), and a more lenient approach, which rules that water suitable for laundry and similar uses is considered usable (Rashba, Avodas Hakodesh, Beis Nesivos 1:14:90 and 3:3:144; Ritva, Eruvin 24a).

In today’s world, this dispute would, seemingly, have a very common application. The run-off from rainstorms in suburbia crosses fertilized and pesticide-treated lawns. This water is definitely unsafe to drink. As a result, water accumulating to an appreciable depth over a large area could invalidate an eruv. However, when the water looks clear and is therefore suitable for laundry use, the Rashba would rule that it would not invalidate the eruv, even if it is deep and covers a large area. Thus, whether this water invalidates the eruv should be dependent on the dispute between Rashi and the Rasha.

How do we rule?

There is an interesting halachic curiousity that results here. Two of the most respected late halachic authorities are the Aruch Hashulchan and the Mishnah Berurah. In the vast majority of halachic issues, the Aruch Hashulchan rules more leniently than does the Mishnah Berurah. However, this is one of the instances in which the Mishnah Berurah (Shaar Hatziyun 358:81) rules more leniently, permitting carrying within an enclosed area that contains non-potable water that may be used for laundry or for animals to drink. The Aruch Hashulchan (358:23) requires that the water be potable.

Water seclusion

What does one do if there is an area of land covered by water in a way that it has the halachic status of a carmelis? The halachah is that, as in the instance of other areas that are not mukaf ledirah, carrying is prohibited in the adjacent residential area only when the area covered by water is not separated by a mechitzah. For example, a stream that contains unusable water runs through an area surrounded by an eruv. Does this render the entire eruv pasul?

One possible solution: To construct a tzuras hapesach that separates the prohibited area from the permitted.

A second possible solution: If the banks of the stream are sufficiently steep, these banks themselves serve to divide the water area from the eruv area and no further adaptation is necessary.

The city eruv

At this point, let us examine the first question I noted above:

“Can the eruv fences, walls, and wires be checked religiously every week, yet the eruv is invalid?”

We now are equipped to answer this question. Indeed, if the area within the eruv includes a large area that is planted or contains non-usable water, that area must be cordoned off from the eruv area in a halachically acceptable fashion. This requires essentially creating some type of halachically-approved divider. Otherwise, the eruv is invalid, and one may not carry there.

Thus, even if an eruv’s perimeters somehow, miraculously, survived the onslaught of a hurricane of the magnitude of Sandy, one will still not be permitted to carry within the eruv if there are areas of deep, unusable water that are more than ~5500 square feet.

Planting and the city eruv

Some authorities rule that planting an area is less of a problem in a city eruv than it is in someone’s private area. This is based on the reasoning, mentioned in the Gemara, that planting in a karpif invalidates an individual’s residential “wall.” However, if an entire city was enclosed, the planting of one individual cannot invalidate the enclosure. (Shu’t Dvar Shmuel #259, who introduces this approach, described planting which, by its nature is temporary, inside a city wall. It may not follow that this can be compared to a modern city and its eruv.) There are authorities who dispute this approach and rule that planting invalidates any type of enclosure (Maamar Mordechai 358:14; Chazon Ish, Orach Chayim 88:25).

Does an overgrown area invalidate an eruv?

Thus far, we have learned how planting or water can invalidate an eruv. What is the halachah if an area becomes overgrown with weeds or other shrubbery? Will this invalidate an eruv?

The late authorities debate whether only a planted area invalidates an eruv, or even an area that becomes overgrown on its own. I leave this question for the local eruv committee to discuss with its halachic authorities.

Do people live in the zoo?

The preceding discussion about mukad ledirah serves as an introduction to understanding the question, “Do people live in the zoo?” a practical question that was raised as early as the eighteenth century. The author of a series of scholarly Torah works, the Ohr Chodosh, Rabbi Elazar ben Elazar, sent a halachic inquiry to his mechutan, the Noda Biyehudah, Rav Yechezkel Landau, the chief rabbi of Prague. Where the Ohr Chodosh was then rav, in Cologne, there was a menagerie of wild animals within the area that they wanted to include within the town’s eruv. Based on his analysis of the dfference between the cases that are considered mukaf ledirah and those that are not, the Ohr Chodosh wanted to permit the zoo area as mukaf ledirah. He begins his analysis with the question:

Why is a vegetable garden or wood storage area considered non-residential, and yet an area in which animals are penned (a dir) is treated as residential?

The Ohr Chodosh, himself, felt that the dwelling of an animal is considered a residential use, and that this is true even regarding the dwellings of wild animals. Therefore, if someone builds a zoo with enclosures for the tigers, lions, bears and other species, each enclosure has the status of mukaf ledirah and can be more than a beis sasayim without prohibiting carrying.

A different scholar, identified in the responsum simply as Rabbi Nissan, disagreed with the Ohr Chodosh, contending that animal pens are considered mukaf ledirah only when they include a hut or other type of residence where the shepherd lives. He notes that Rabbeinu Yonasan, the major commentary on the Rif on Eruvin, mentions this distinction. The Ohr Chodosh retorted that he found this restriction, that a dir is considered mukaf ledirah only when it contains a residence of sorts for the shepherd, in no other halachic source, and therefore concluded that Rabbeinu Yonasan’s ruling is a minority opinion. The Ohr Chodosh contended that most authorities would accept his analysis.

On Rosh Chodesh Nisan 5548 (1788), the Noda Biyehudah answered the letter of the Ohr Chodosh, siding with Rabbi Nissan. Although the Noda Biyehudah agrees that the other authorities may not accept Rabbeinu Yonasan’s requirement of a guard hut, the key difference between a dir and a vegetable patch is that a dir requires a human presence, whereas a vegetable patch does not require a human presence. The Noda Biyehudah contends that an enclosure for wild animals will not be considered mukaf ledirah, and will be prohibited if the area is more than a beis sasayim, since people do not dwell among wild animals.

In his responsum, the Noda Biyehudah does not discuss what is the exact difference between a dir and a ginah, but other authorities do. The Tosafos Shabbos explains the difference to be that a dir is used by people at night, whereas a ginah is used only during the daytime. The Biur Halachah explains the dissimilarity in a different way, contending that a dir is adjacent to the house, and includes milking and other uses that are domestic. Therefore, its use is incorporated with the use of the residence.

Roofed

From the case of burgenin and some others, it appears that even a roofed area can be considered not mukaf ledirah. This is the opinion of most halachic authorities, although one major authority feels that burgenin is an exception, and that most roofed areas can be considered mukaf ledirah.

Based on this discussion, one can ask whether a warehouse, larger than a beis sasayim, that does not contain any type of residence, is considered mukaf ledirah. The use of a warehouse is not domestic and therefore could be conceived as not mukaf ledirah.

This question involved a dispute between the Mishnah Berurah and the Chazon Ish. The Mishnah Berurah holds that since a warehouse is a strongly constructed building, it qualifies as mukaf ledirah, regardless as to why it was constructed and how it is currently used. The Chazon Ish challenges this position, insisting that unless a structure includes some place to be used for sleeping, it is not considered mukaf ledirah, unless it meets one of the categories that the Mishnah or Gemara qualify as mukaf ledirah.

The dispute between the Mishnah Berurah and the Chazon Ish should affect only the status of the warehouse itself, and that only if it is larger than a beis sasayim. However, since a warehouse is completely enclosed its status will not prohibit an adjacent area. Thus, the area within the eruv surrounding the warehouse will remain unaffected by its status.

Shuls, batei medrash and bathhouses

The Aruch Hashulchan notes that shuls, batei medrash and bathhouses are all buildings whose purpose is not for residential purpose. One is not permitted to use a shul or a beis medrash for personal use, and a bathhouse is also not used for typical residential use. The Aruch Hashulchan therefore concludes that all of these areas do not qualify as mukaf ledirah, unless they include some type of residence for the building’s caretaker.

Conclusion

Rav Samson Raphael Hirsch (Shemos 20:10) notes that people mistakenly think that work is prohibited on Shabbos in order to provide a day of rest. This is incorrect, he points out, because the Torah does not prohibit doing avodah, which connotes hard work, but melachah, which implies purpose and accomplishment. Certainly no more calories are expended when carrying from a reshus hayachid to a reshus harabim than when carrying a heavier item a greater distance within a reshus hayachid; yet, the first activity desecrates Shabbos and the second is permitted.

The goal of Shabbos is to emphasize Hashem’s rule as the focus of creation by refraining from our own creative acts (Rav Samson Raphael Hirsch Commentary to Shemos 20:11). Creating a beautiful Shabbos entails much planning and organization, realizing that preparation for Shabbos includes studying all the melachos of Shabbos. This helps us have a greater appreciation of Shabbos, and to get the maximum joy out of this special day.

Do People Live in the Zoo?

PENTACON DIGITAL CAMERAQuestion #1: Checking inside the eruv

“Can the eruv fences, walls, and wires be checked religiously every week, yet the eruv is invalid?”

Question #2: Shabbos in a warehouse

“May one carry in a warehouse on Shabbos?”

Question #3: Do people live in the zoo?

What do the previous two questions have to do with the title of this article?

Answer: Invalidating an eruv from inside

With the direction of his rav, Yankel has joined the committee of makers and shakers working on building an eruv in his hometown. He now knows that the area in which he currently lives has the halachic status of a karmelis, an Aramaic word meaning an area in which one may not carry, but which can be enclosed to permit carrying. Creating the enclosure in a halachically approved way is what one does when building an eruv.

One of the benefits of his new project is that Yankel learns much about the laws of eruv. Among the laws he discovers is an entire area of halachah with which he was not familiar – that enclosing an area does not always permit carrying. Often, there is an area within the eruv that precludes carrying there. These areas are often called karpif, although Yankel discovers that this term is also not really accurate. As a result of his curiosity, he studies the relevant source material in the second chapter of Mesechta Eruvin, a topic that he, like most people, had never studied during his years in yeshivah.

What is a karpif?

Although min hatorah one may carry within any enclosed area, Chazal permitted carrying in a large area only when the enclosing of the area serves a residential purpose, which is called mukaf ledirah. If the enclosure was not mukaf ledirah, the area inside is also considered a karmelis in which one may not carry.

Technically, the word karpif means an enclosure outside the city in which one stores felled wood (Rashi, Eruvin 18a). However, the term is generally used to mean an enclosed area that is not mukaf ledirah.

Yankel learned that if an enclosure does not serve a residential purpose, one may carry within it only when it encloses an area that is no larger than the size of the courtyard of the mishkan, which was 50 amos (cubits) wide and 100 amos long, the size of 5000 square amos (Mishnah Eruvin 23a). An area this size is called a beis sasayim, an old farmers’ term based on how much seed they would plant there, and equals approximately 1000* square meters or 10,000-11,000 square feet. For the balance of this article, I will refer to an area larger than a beis sasayim, that is, one that contains more than 5000 square amos, as a large area, and any area smaller than this as a small area.

There is another factor that must be met to permit carrying in a small area that is not enclosed for residential use – its length may not exceed twice its width by more than one amoh (Mishnah, Eruvin 23a).

Why is a small karpif permitted?

Why may one carry in an area that is not mukaf ledirah when it is 5000 square amos or smaller? Was this size chosen arbitrarily?

Chazal permitted carrying in a small area, even when it is not mukaf ledirah, for the following reason: Since no one is permitted to live in the courtyard of the mishkan, the curtains that surround it do not make it mukaf ledirah. This would mean that carrying within the mishkan would be under the heading of a rabbinic prohibition. Yet this carrying was necessary on Shabbos for the regular functioning of the mishkan. Rather than treat the mishkan as an exception to the halachah, Chazal permitted carrying in any area that is this small, even when it is not mukaf ledirah (see Graz, Orach Chayim 358:3).

What is mukaf ledirah?

The definition of what qualifies as mukaf ledirah and what does not is, at times, not obvious. The Gemara (Eruvin 22a) itself states that there are instances when an enclosed area is roofed and resembles a building, yet it is considered not mukaf ledirah, and there are places that are open-air and yet have the status of mukaf ledirah. The Mishnah (Eruvin 18a) mentions four cases that qualify as mukaf ledirah, even though (according to Rashi) there is no roof over them. They are:

(1) Dir — a corralled area that one intends to plant eventually. At the moment, it is fallow, and one is grazing one’s livestock there, so that they naturally fertilize the field.

(2) Sohar, which is, according to Rashi, an area where the townspeople graze their animals, and, according to the Rambam, a prison.

(3) Muktzah — a backyard area.

(4) Chatzeir, a front yard.

The Ritva (Eruvin 22a) explains that the list is progressively more obvious; meaning that the first case, that of dir, is the least obvious “residential” area. Indeed, much halachic literature is devoted to explaining why an area enclosed for animals is considered residential, when, as we will soon see, areas enclosed for trees or vegetation are not.

Non-residential enclosures

Our next objective is to define what is considered a non-residential enclosure, eino mukaf ledirah, in which one may not carry unless it is small, as defined above. The Mishnah and the Gemara teach that several different types of enclosed areas are not mukafim ledirah. As I mentioned above, one of these is a karpif, an enclosure outside the city in which one stores felled wood (Rashi, Eruvin 18a). Similarly, a fenced-in orchard (Rambam, Hilchos Shabbos 16:1, based on Eruvin 25b), a vegetable patch or a grain field (Mishnah Eruvin 18a; Eruvin 23b) are not mukaf ledirah, even when they contain huts, called burgenin, for the watchmen (Eruvin 22a). In all of these instances, the fence built around the perimeter does not serve a residential need. Even the watchman’s hut is there not to serve as a residence, but to allow the watchman to remain nearby (Rashi, Eruvin 15a). (We should note that some authorities [Tosafos Shabbos, 358:1; Pri Megadim, Eishel Avraham 358:1] contend that if the watchman sleeps overnight in the hut, it is considered a residence. In their opinion, a burgenin is considered not mukaf ledirah because one uses it only in the daytime.)

We need to understand exactly why certain uses are considered residential, and others are not. However, prior to explaining these ideas, we need to clarify another aspect of this discussion.

Mixed neighborhoods

What is the halachah if an enclosure comprises both an area considered residential and an area that is not? For example, Yankel’s neighbor, Shmerel, has a large fenced-in backyard, which his family uses predominantly for barbecues and other recreation. It sounds as if this area should be treated as mukaf ledirah, even if it is larger than 5000 square amos. Indeed, its proximity to the house and its use would make this backyard mukaf ledirah.

However, this yard also includes a section planted with various spices and vegetables. As we learned above, a planted area is not mukaf ledirah. Do we consider the entire yard mukaf ledirah or not? May Shmerel’s family carry in the backyard? In the course of Yankel’s studying the laws of Eruvin, he discovered that carrying in his neighbor’s fenced-in yard might be prohibited!

A breached eruvNifratz bemilu’oh

To answer these questions, we need to explain a principle, called nifratz bemilu’oh, literally, breached in its entirety. Whenever an area in which one would otherwise be permitted to carry is open to an area where carrying is forbidden, the halachic result is that one may not carry in the otherwise permitted area (see Eruvin 25b). Thus, if it is prohibited to carry in the planted area, and the recreational part of Shmerel’s yard is nifratz bemilu’oh to the planted area, one cannot carry in any part of Shmerel’s yard (Shulchan Aruch, Orach Chayim 358:10). As we will soon see, this law has major ramifications for city eruvin also.

What is called “breached?”

Our next question, germane both to Shmerel’s yard and to our city eruv, is: How big a breach prohibits carrying?

There are two ways that a breach forbids carrying. One is when it is greater than ten amos, approximately seventeen feet or five meters. The other way is when the breach is smaller than ten amos but it comprises an entire side of the otherwise-permitted mukaf ledirah area. For example, if an otherwise-permitted rectangularly-shaped area is mukaf ledirah on three of its sides, but the remaining unwalled side opens to an area in which carrying is forbidden, even if the unwalled side is less than 10 amos wide one may not carry in the mukaf ledirah area.

In terms of Shmerel’s yard, this means that if the recreational part is not isolated from the garden, and the garden is large enough to prohibit carrying, the entire yard is prohibited. The same concept is true in a city eruv, as we will soon see.

How large a garden?

Before we can issue a ruling regarding Shmerel’s garden, we need one more piece of information. How large a garden will prohibit carrying?

The Gemara (Eruvin 23b-24a) states that if a planted area is larger than 5000 square amos, one may not carry in any part of the backyard. Even when the planted area is smaller than 5000 square amos, if the planted part is larger than the rest of the yard and the entire yard is larger than 5000 square amos, one may not carry in any part of it.

Healing a breach

Yankel and Shmerel measure the vegetable garden and the yard and discover that, lo and behold, one may not carry in Shmerel’s yard. Is there any way to fix the above problem to permit carrying within the recreational part of the yard?

Yes, there are at least two ways that one can do this. The first is to separate the recreational area from the planted area, and the second is to subdivide the planted area until it is small enough not to create a halachic issue. There are several ways of implementing either of these methods, but discussing them is beyond the scope of this article.

A flower garden

What is the halachah if Shmerel’s garden consists of a flower garden, rather than a vegetable patch? Does his flower garden invalidate the area for carrying, just as the vegetable garden did?

The halachic issue here is the following: People do not live in vegetable patches, but they do enjoy looking and smelling pretty and fragrant flowers. Is this a sufficient reason to consider a flower garden mukaf ledirah?

This matter is a subject of dispute, with different authorities on, shall we say, different sides of the fence. Although most authorities rule that a flower garden does not present a problem (see also Meiri, Eruvin 24a), the Divrei Chayim of Sanz (Shu’t Divrei Chayim, Orach Chayim 2:28) and the Sha’ul Umeishiv (Shu’t 3:131) were among the authorities who ruled that a flower garden will prohibit an eruv. Someone with a similar shaylah should refer it to his own rav or posek.

Fair lawn

As I mentioned above, the Gemara rules that a large, planted area for vegetables or grains will invalidate the eruv. Several halachic authorities say that a grass cover does not invalidate an eruv, since people relax by sitting or lying on the grass. However, can this logic apply when someone does not permit anyone to walk across their expensively tended lawn? This phenomenon, not uncommon in a modern suburban setting, implies that the contemporary lawn of this nature may not be considered mukaf ledirah and can therefore create a problem, if it is larger than a beis sasayim. I leave this question for the eruv movers and shakers to discuss with their posek.

Fenced first

Another halachic factor is that mukaf ledirah requires that the enclosure must have been constructed initially for residential use. This is called pasach u’le’besof hukaf, literally, he opened the entrance first and then afterwards enclosed the area (Eruvin 24a). However, if the area was enclosed when it did not yet have a residential use, providing it with a residential purpose later will not render the area one in which carrying is permitted.

For example, if Shmerel had originally decided to fence in his large yard because he wanted to plant vegetables, and only later decided to use it for domestic purposes, one may not carry in the yard, since its enclosure was originally not for domestic use. (There are ways to rectify such a situation, but this is a topic that we need to leave for a different time.)

Bitul mechitzos

We have yet to discuss another related question: What is the halachah if an area was originally mukaf ledirah, and then someone planted within the mukaf ledirah area? Does this now render the area a karmelis and prohibit carrying? As an example, let us imagine the following scenario: When Shmerel built the fence around his yard, his intention was for residential purposes, and it therefore had a status of mukaf ledirah. At this point, one could carry in the yard. Later, Shmerel decided to plant a large vegetable garden in the yard. Do we say that the yard remains permitted?

The halachah is that planting grain or vegetables invalidates the enclosure, and it is prohibited to carry in his yard.

However, there is an interesting halachah here. Not all planting invalidates the external walls. For example, the Gemara (Eruvin 23b) states explicitly that if one plants a large area of trees, one may continue carrying in the area. This ruling is very interesting, especially in light of the fact that a fence surrounding an orchard is not considered mukaf ledirah.

Trees versus veggies

What is the different between trees, which do not invalidate the eruv, and grain and vegetables, which do?

Rashi (Eruvin 23b) explains that people do not live in a vegetable patch; however, people will walk through an orchard to enjoy the shade. Thus, the planting of trees does not remove the designation of mukaf ledirah from the area.

As I noted above, the latter halachah applies only when one planted trees in an area that was already mukaf ledirah. In other words, there is a difference between enclosing the area, which requires that it initially is mukaf ledirah, and changing its status once it was mukaf ledirah. Enclosing an orchard is not considered mukaf ledirah.

We will continue this article next week…
