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…
