Shabbat 1:49

['The acts of carrying out from a public domain into a private domain or vice versa, which are prohibited on Shabbat, are primarily two basic actions that comprise four cases from the perspective of a person inside a private domain, and two basic actions that comprise four cases from the perspective of a person outside, in a public domain. The mishna elaborates: How do these eight cases take place? In order to answer that question, the mishna cites cases involving a poor person and a homeowner. The poor person stands outside, in the public domain, and the homeowner stands inside, in the private domain. The poor person lifted an object in the public domain, extended his hand into the private domain, and placed the object into the hand of the homeowner. In that case, the poor person performed the prohibited labor of carrying from the public domain into the private domain in its entirety. Or, the poor person reached his hand into the private domain, took an item from the hand of the homeowner, and carried it out into the public domain. In that case, the poor person performed the prohibited labor of carrying out from the private domain into the public domain in its entirety. In both of these cases, because the poor person performed the prohibited labor in its entirety, he is liable and the homeowner is exempt. The mishna cites two additional cases. In these, the prohibited labor is performed by the homeowner, who is in the private domain: The homeowner lifted an item in the private domain, extended his hand into the public domain, and placed the object into the hand of the poor person. In that case, the homeowner performed the labor of carrying out from the private domain into the public domain in its entirety. Or, the homeowner reached his hand into the public domain, took an object from the hand of the poor person, and carried it into the private domain. In that case, the homeowner performed the labor of carrying from the public domain into the private domain in its entirety. In both of those cases, because the homeowner performed the prohibited labor in its entirety, he is liable and the poor person is exempt. There are four additional cases where neither the homeowner nor the poor person performed the labor in its entirety, and therefore neither is liable: The poor person extended his hand into the private domain and either the homeowner took an object from his hand and placed it in the private domain or the homeowner placed an object into the hand of the poor person, and the poor person carried the object out into the public domain. In those cases and the two that follow, the act of transferring the object from one domain to another was performed jointly by two people, the poor person and the homeowner. Because each performed only part of the prohibited labor, both of them are exempt. So too, in a case where the homeowner extended his hand into the public domain and, either the poor person took an object from the homeowner’s hand and placed it in the public domain or the poor person placed an object into the homeowner’s hand and the homeowner carried the object into the private domain. Because each performed only part of the prohibited labor, both of them are exempt.', 'After having dealt with the limited and defined topic of the halakhot of carrying out on Shabbat, the mishna begins to deal with the halakhot of Shabbat chronologically, beginning with activities that one may not perform prior to the onset of Shabbat. With regard to one’s daily conduct, the mishna says: A person may not sit before the barber adjacent to the time of minḥa until he recites the afternoon prayer. And a person may not enter the bathhouse and may not enter to work in a tannery [burseki]. And he may neither begin to eat a meal nor to sit in judgment until he prays. And however, if they already began engaging in those activities, they need not stop and recite the Amida prayer. The tanna articulated a principle: One stops engaging in all of these activities to recite Shema and one does not stop to recite the Amida prayer.', 'This mishna deals with various decrees, especially with regard to the halakhot of Shabbat, which were issued in order to distance a person from transgressions that he is liable to commit through habit and routine. The mishna said: The tailor may not go out with his needle adjacent to nightfall on Shabbat eve, lest he forget that he is carrying the needle and go out with it to the public domain even after Shabbat begins. And, similarly, the scribe [lavlar] may not go out with his quill[kulmos] for the same reason. And one may not shake his clothes on Shabbat to rid them of lice; and one may not read a book by candlelight, so that he will not come to adjust the wick of the lamp. However, in truth they said an established halakha: The attendant sees where in the book the children under his supervision are reading in the Torah, even by candlelight on Shabbat. However, he himself may not read. Similarly, the Sages issued a similar decree with regard to other halakhot, as they said: The zav may not eat even with his wife the zava, despite the fact that they are both ritually impure, because, by eating together, they will come to excessive intimacy and become accustomed to sin.', 'And these are among the halakhot that the Sages, who went up to visit him, said in the upper story of Ḥananya ben Ḥizkiya ben Garon. The precise nature of these halakhot will be explained in the Gemara. These halakhot are considered one unit because they share a distinctive element. Since many Sages were there, among them most of the generation’s Torah scholars in Eretz Yisrael, they engaged in discussion of various halakhot of the Torah. It turned out that when the people expressing opinions were counted, the students of Beit Shammai outnumbered the students of Beit Hillel, and they issued decrees with regard to eighteen matters on that day in accordance with the opinion of Beit Shammai.', 'In this mishna there is a fundamental dispute between Beit Hillel and Beit Shammai: Must one begin refraining from actions prohibited on Shabbat on Shabbat eve? Or, may one initiate an action prior to Shabbat, even if he knows that it will continue on its own on Shabbat itself? These are the details of that dispute: Beit Shammai say: One may only soak dry ink in water and dry plants, which produce dyes, in water and vetch for animal food to soften them in water on Shabbat eve, adjacent to Shabbat,if there is clearly sufficient time for them to soak for their designated purpose while it is still day, before Shabbat begins, and their continued soaking on Shabbat will have no effect. And Beit Hillel permit doing so.', 'Beit Shammai say: One may only place bundles of combed flax inside the oven on Shabbat eve if there is sufficient time so that they will be heated while it is still day. And one may only place wool into the dyer’s kettle if there is sufficient time for the wool to absorb the dye while it is still day. And Beit Hillel permit doing so. Beit Shammai say: One may spread traps for an animal and birds and fish only if there is sufficient time remaining in the day for them to be trapped in them while it is still day, and Beit Hillel permit doing so even if there is not sufficient time remaining in the day.', 'Beit Shammai say: One may only sell an item to a gentile on Shabbat eve, and one may only load a burden on his donkey with him, and one may only lift a burden on him if there remains sufficient time for the gentile to arrive to a near place prior to Shabbat, and the Jew will play no role in the performance of a prohibited labor by the gentile on Shabbat. And Beit Hillel permit doing so.', 'Beit Shammai say: One may not give skins to a gentile tanner, nor clothes to a gentile launderer, unless there is sufficient time for work on them to be completed while it is still day, before Shabbat begins. And in all of them Beit Hillel permit doing so with the sun, i.e., as long as the sun is shining on Friday. ', 'Rabban Shimon ben Gamliel said: The ancestral house of my father, the dynasty of Nesi’im from the house of Hillel, was accustomed to give its white clothes to a gentile launderer no fewer than three days before Shabbat. And, however, these, Beit Shammai, and those, Beit Hillel, agree that, ab initio, one may load the beam of the olive press on the olives on Shabbat eve while it is still day, so that the oil will continue to be squeezed out of the olives on Shabbat. So too, one may load the circular wine press to accelerate the process of producing wine from the grapes.', 'This mishna enumerates actions that may only be performed on Shabbat eve if the prohibited labor will be totally or mostly completed while it is still day. One may only roast meat, an onion, or an egg if there remains sufficient time so that they could be roasted while it is still day. One may only place dough to bake into bread in the oven on Shabbat eve at nightfall, and may only place a cake on the coals, if there is time enough that the surface of this cake or bread will form a crust while it is still day. Rabbi Eliezer says: Enough time so that its bottom crust should harden, which takes less time.', 'However in a case that is an exception, one may, ab initio, lower the Paschal lamb into the oven on Shabbat eve at nightfall, so that its roasting is completed on Shabbat if Passover eve coincides with Shabbat eve. And one may, ab initio, kindle the fire in the bonfire of the Chamber of the Hearth in the Temple on Shabbat eve, adjacent to the start of Shabbat, and allow the fire to spread afterward throughout all the wood in the bonfire. And, however, in the outlying areas, meaning in all of Eretz Yisrael outside the Temple, it is prohibited to light a bonfire on Shabbat eve, unless there is sufficient time for the fire to take hold in most of the bonfire, while it is still day. Rabbi Yehuda says: With a bonfire of coals, even in the outlying areas one is permitted to light the fire on Shabbat eve at nightfall, even if the fire only spread to any amount of the bonfire. The coals, once they are kindled, will not be extinguished again, and there is no concern lest he come to tend to them on Shabbat.']
