Question #1: Why then?
“After sunset on a Friday evening, may I ask a non-Jewish person to turn on the lights?”
Question #2: Until when?
“May I toivel dishes, glasses and silverware during the same twilight period?”
Question #3: Challah
“May I separate challah during bein hashemashos?”
Introduction: Twilight laws
As we are all aware, the halachic day begins and ends at nightfall. But at what exact moment does one day march off into history and its successor arrive with its banner unfurled? Is it before sunset, at sunset, when the stars appear, or dependent on some other factor? And, if a day begins when the stars appear, which stars and how many? Does the amount of time after sunset vary according to longitude and/or season of the year? And does it, perhaps, vary according to the amount of humidity in the atmosphere?
There is much discussion in the Gemara and the poskim concerning many of these issues, some of which I have written about previously. This article will discuss the halachic rules that apply during the period of time called bein hashemashos, which is the term used to refer to the twilight interval when we are uncertain whether it is still day or already night. Of particular concern is what is the halacha of this time on Friday evening, when it is unclear whether or not Shabbos has already begun. Does bein hashemashos have the exact same halachic status as the time that is definitely Shabbos, or does its questionable status allow any lenience? The answer is that, under extenuating circumstances, some lenience is allowed. We will see that the definition of “extenuating” for these purposes is rather moderate.
The earliest sources
In several places, the Mishnah, the Gemara and the poskim explain that certain activities that are prohibited on Shabbos are permitted during bein hashemashos of Friday evening. We will begin our research with a Mishnah (Shabbos 34a) that many recite every Friday evening in shul, as the last passage in Bameh Madlikin. There, it teaches: If it is in doubt whether nightfall has already arrived, it is forbidden to separate maaser from produce, when we are certain that it was not yet separated. (Such untithed produce is referred to as tevel.) It is also prohibited to immerse vessels to make them tahor. (Unfortunately, since we are all tamei today, this question is not relevant, but we will soon discuss whether immersing vessels used for food that were previously owned by a non-Jew is permitted during bein hashemashos.) The Mishnah also prohibits kindling lights during bein hashemashos. However, it permits separating maaser from demai produce, about which it is uncertain whether this separation is required. It is permitted during bein hashemashos to make an eiruv chatzeiros, which allows carrying from one’s house to a neighbor’s house on Shabbos. The Mishnah also permits insulating food, hatmanah, using something that does not increase heat (such as clothing), notwithstanding that this is prohibited on Shabbos.
As we will see shortly, there is much discussion among rishonim and early poskim whether we rule according to the conclusions of this Mishnah, or whether we rule more leniently. But first, we need to understand each of the halachic issues that the Mishnah mentions. For example, what is wrong with separating maasros, even on Shabbos itself? Which melacha of Shabbos does this violate?
The Mishnah (Beitzah 36b) prohibits separating maasros on Yom Tov, and certainly on Shabbos. The reason for this prohibition is that, since it makes the food edible halachically, it is viewed as a form of forbidden “repair work.”
Demai has an in-between status. What is demai? In the times of Chazal, observant but poorly educated Jews observed the mitzvos, although some of them would occasionally “cut corners,” violating details of halachos that involve major expense. These people, called amei ha’aretz, were lax predominantly regarding three areas of halacha –the laws of shemittah, the laws of tumah and taharah, and the laws of separating maasros. Although most amei ha’aretz indeed separated maasros faithfully, Chazal instituted that produce purchased from an am ha’aratz should have maaser separated from it, albeit without first reciting the brocha for taking maaser. This produce was called demai, and the institution of this takkanah was because it was difficult to ascertain which amei ha’aretz were separating maasros and which were not. Thus, we treat this produce as a type of safek tevel. For this reason, the brocha for separating maasros was omitted prior to separating maaser from demai because, indeed, most amei ha’aretz separated maasros. In addition, because most amei ha’aretz separated maasros, Chazal allowed other leniencies pertaining to its use; for example, they permitted serving demai produce to the poor or to soldiers in the army.
Because there is a great deal of reason to be lenient relative to demai, the Mishnah permitted separating maasros from it during bein hashemashos (Shabbos 34a). The reason this is permitted is because this separation may not actually be “fixing” anything – it is more than likely that the maasros were already separated.
During bein hashemashos, the Mishnah permitted immersing vessels and other items that had previously become tamei. This immersion is prohibited on Shabbos or Yom Tov, itself, as mentioned in Mesechta Beitzah (Mishnah 17b and Gemara ad loc.). There, the Gemara (Beitzah 18a) cites a four-way dispute why it is prohibited to immerse vessels to make them tahor on Shabbos or Yom Tov. The four reasons are:
1. Someone immersing vessels on Shabbos may inadvertently carry them through a public area. According to this opinion, immersing vessels on Yom Tov was prohibited as an extension of the prohibition of Shabbos.
2. Clothing and cloth that became tamei, and was then toiveled on Shabbos or Yom Tov, could cause someone to squeeze out the water. According to this opinion, immersing pots, plates, silverware and other items that do not absorb water was prohibited as an extension of the prohibition to immerse cloth and other squeezable items.
3. Knowing that someone has time to toivel vessels on Shabbos or Yom Tov, the owner might delay toiveling them until then. This procrastination might then result in foods or other vessels becoming tamei. Banning the immersions on Shabbos or Yom Tov would cause people to immerse the vessels at an earlier opportunity.
4. Immersing vessels to make them usable is considered “repairing” them on Shabbos or Yom Tov.
The rishonim disagree how we rule in this dispute: in other words, which of the four reasons is accepted (see Rif, Rosh, etc.). There are halachic ramifications of this dispute. Although immersing vessels to make them tahor is not a germane topic today, since we are all tamei anyway, the question is raised whether vessels acquired from a non-Jew, which require immersion in a mikveh prior to use, may be immersed on Shabbos and Yom Tov. When we look at the reasons mentioned by the Gemara why Chazal forbade immersing tamei vessels on Shabbos and Yom Tov, we can conclude that some of the reasons should definitely apply to the immersing of vessels for this latter reason, whereas others might not. The Rosh concludes that it is prohibited on Shabbos and Yom Tov to immerse vessels acquired from a non-Jew. (See, however, Shaagas Aryeh #56.) We will discuss shortly whether one can immerse them during bein hashemashos.
During bein hashemashos, any Torah prohibition cannot be performed because of safek de’oraysa lechumrah, the rule that cases of doubt regarding Torah prohibitions are treated stringently. The Mishnah’s example of this is kindling lights, which is certainly forbidden during bein hashemashos.
Hatmanah — Insulating food
The Gemara explains that the Mishnah’s last ruling, insulating food, is permitted bein hashemashos because of a specific reason applicable only to its case. Since explaining the details of this rabbinic injunction, called hatmanah, would take us far afield, we will forgo that discussion in this article.
Rebbe and the Rabbanan
Up until this point, I have been explaining the Mishnah in Bameh Madlikin. However, elsewhere, the Gemara (Eruvin 32b) cites a dispute between Rebbe and the Rabbanan, in which Rebbe contends that all rabbinic prohibitions may be performed during the bein hashemashos period, whereas the Rabbanan prohibit this. The obvious reading of the Mishnah in Bameh Madlikin is that it follows the approach of the Rabbanan who prohibit performing most rabbinically prohibited acts during the bein hashemashos period, and, indeed, this is how Rashi explains that Mishnah. However, the Gemara (Eruvin 32b-34b) demonstrates that the Mishnah there in Eruvin follows the opinion of Rebbe. On its own, this is not a halachic concern, since there are instances in which different Mishnayos follow the opinions of different tana’im. The practical question that needs to be decided is whether we indeed rule according to the Rabbanan’s position as stated in the Mishnah in Bameh Madlikin, or whether we follow Rebbe’s more lenient ruling. The conclusion of the Gemara in Eruvin implies that the halacha follows the opinion of Rebbe, and not that of the Rabbanan.
Among the rishonim, we find variant halachic conclusions regarding this question (Rashi, Shabbos 34a s.v. safek; Rambam, Hilchos Shabbos 24:10 and Hilchos Eruvin 6:9; Tur Orach Chayim 342; Beis Yosef Orach Chayim 261 and 342). The Shulchan Aruch (Orach Chayim 342) concludes according to the Rambam’s opinion, ruling that during bein hashemashos Chazal did not forbid anything that is prohibited because of a rabbinic injunction, provided that there is some mitzvah involved or that there were extenuating reasons why it was not performed on erev Shabbos. The Shulchan Aruch mentions, specifically, that it is permitted during bein hashemashos to climb a tree on Rosh Hashanah to get a shofar in order to perform the mitzvah, although it is prohibited to climb a tree on Yom Tov itself even if, as a result, you will be unable to blow shofar. Returning to our first question (“After sunset on a Friday evening, may I ask a non-Jewish person to turn on the lights?”, the Shulchan Aruch also permits asking a non-Jew to kindle a light during bein hashemashos. The Mishnah Berurah 261:17 permits asking him, even if you already accepted Shabbos.
Similarly, the Magen Avraham (261:6) permits separating maasros during bein hashemashos, if you do not have enough food ready for Shabbos. (The Ketzos Hashulchan [75:5, 6 in Badei Hashulchan] explains that the situation is such that he does not have enough fruit or vegetables to have an enjoyable Shabbos meal.) It is very interesting that the Magen Avraham permits this, because the Mishnah at the end of Bameh Madlikin thatwe quoted above expressly prohibits separating maasros during bein hashemashos. Nevertheless, the Magen Avraham permits this separating of maasros, since we rule according to Rebbe, not like the Mishnah.
Toiveling during bein hashemashos
With this background, let us examine the second of our opening questions: is it permitted during the bein hashemashos period to toivel dishes, glasses and silverware purchased from a non-Jew? Assuming we conclude, like the Rosh does, that it is prohibited to toivel these items on Shabbos or Yom Tov, which is the common practice, someone who has no others to use on Shabbos or Yom Tov may toivel them during bein hashemashos (Magen Avraham 261:6).
There is much discussion among halachic authorities whether it is permitted to separate challah during bein hashemashos, if you realize that you forgot to do so before. As we will see shortly, the Magen Avraham (261:2) prohibits separating challah bein hashemashos, whereas other authorities qualify this. To explain their halachic conclusions, we need to provide some background to the laws of separating challah.
Although people are often surprised to discover this, challah is categorized under the mitzvos ha’teluyos ba’aretz, the agricultural mitzvos that apply min haTorah only in Eretz Yisroel. The requirement of separating challah from dough made in chutz la’aretz is a rabbinic requirement. However, when implementing this requirement, Chazal instructed that the mitzvah be performed in a different way from how it is observed in Eretz Yisroel. Dough made in Eretz Yisroel that has not yet had its challah portion separated has the halachic status of tevel and may not be eaten. Dough made in chutz la’aretz does not become tevel. There is a mitzvah to separate challah, but this mitzvah can be fulfilled even after most of the dough has been eaten.
Therefore, should one realize on Shabbos that challah was not separated from dough made in Eretz Yisroel, the bread cannot be eaten because it is tevel. However, if the dough was made in chutz la’aretz, the bread can be eaten on Shabbos, and the challah separated after Shabbos. To do this, you must make sure that you keep some of the bread until after Shabbos, and then separate challah from what was set aside.
Reverse the law
The result of this halacha is that dough produced in chutz la’aretz does not require that its challah is separated in order to permit eating it on Shabbos, whereas dough produced in Eretz Yisroel does. We therefore have an anomalous conclusion regarding whether the challah may be separated during bein hashemashos. Challah may not be separated from dough made in chutz la’aretz, because you can wait to separate the challah until after Shabbos. The later authorities explain that this is the intention of the ruling of the Magen Avraham (261:2). However, when the dough was prepared in Eretz Yisroel and challah was not taken, it will be forbidden to eat the bread on Shabbos. Therefore, when you realize that you forgot to separate challah, and you are relying on that bread for your Shabbos meals, you may separate the challah during bein hashemashos (Machatzis Hashekel 261:2; Pri Megadim, Eishel Avraham 261:2; Mishnah Berurah 261:4).
We can now address the third of our opening questions: “May I separate challah during bein hashemashos?” The answer is that if the dough was mixed in chutz la’aretz, I may not, but I may eat the baked bread during Shabbos, as long as I leave some of it for after Shabbos and then separate challah retroactively. On the other hand, if the dough was made in Eretz Yisroel, I may therefore not eat it without first separating challah, and I may separate the challah during bein hashemashos.
The Gemara teaches that the rabbinic laws are dearer to Hashem than the Torah laws. In this instance, we see that Chazal provided lenience to permit otherwise prohibited activities to be done during the bein hashemashos period.
Rav Samson Raphael Hirsch (Shemos 20:10) notes that people mistakenly think that work is prohibited on Shabbos, in order for it to be a day of rest. He points out that the Torah does not prohibit doing avodah, which connotes hard work, but melachah, activities or actions which bring purpose and accomplishment. Shabbos is the day on which we refrain from constructing and altering the world for our own purposes. The goal of Shabbos is to allow Hashem’s rule to be the focus of creation, by refraining from our own creative acts (Shemos 20:11).
