1One may move all metal lamps on Shabbat, even old ones, because they do not become repugnant like earthenware lamps, except for a metal lamp that one kindled on that same Shabbat and that was burning when Shabbat began, which it is prohibited to move for the entire Shabbat due to the prohibition against extinguishing.
2The Gemara rejects that analogy. And perhaps it is different there, in the case of the burning lamp, as he set it aside by direct action when he kindled the lamp. By contrast, in the case of an animal, he did not set it aside, and therefore, perhaps once it is slaughtered it is permitted.
3Rather, Rav Ashi said: When Rav said that the halakha that consumption of the animal is prohibited for that day is the opinion of Rabbi Yehuda, the reference is to the opinion of Rabbi Yehuda with regard to one who cooks, as we learned in a baraita : With regard to one who cooks on Shabbat, if he did so unwittingly, he may eat what he cooked. If he acted intentionally, he may not eat what he cooked. This is the statement of Rabbi Meir.
4Rabbi Yehuda says: If he cooked the food unwittingly, he may eat it at the conclusion of Shabbat, as the Sages penalized even one who sinned unwittingly by prohibiting him from deriving immediate benefit from the dish that he cooked. If he cooked it intentionally, he may never eat from it.
5Rabbi Yoḥanan HaSandlar says: If he acted unwittingly, the food may be eaten at the conclusion of Shabbat by others, but not by him. If he cooked the food intentionally, it may never be eaten, neither by him nor by others. According to Rav, the mishna is referring to a case where one slaughtered the animal unwittingly. According to Rabbi Yehuda, the slaughter is valid but it is prohibited to eat the animal on Shabbat.
6The Gemara challenges this: And let us interpret the mishna as referring to a case where he slaughtered the animal intentionally, and explain that it is in accordance with the opinion of Rabbi Meir, who rules that eating the animal in such a case is permitted only after the conclusion of Shabbat.
7The Gemara responds: That possibility should not enter your mind, as the case of slaughter on Shabbat is juxtaposed to and taught in a manner similar to the case of slaughter on Yom Kippur. Just as with regard to slaughter on Yom Kippur, it is no different whether one slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day due to the fast, so too here, with regard to slaughter on Shabbat, it is no different whether he slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day. Rabbi Meir, though, deems it permitted for one who cooked unwittingly to eat the cooked food on Shabbat.
8The Gemara asks: And can you interpret the mishna as referring to a case of unwitting slaughter and in accordance with the opinion of Rabbi Yehuda? But isn’t it taught in the mishna: Although he is liable to receive the death penalty? One is liable to be executed only if he intentionally performs labor on Shabbat. The Gemara answers that this is what the mishna is saying: Although if he slaughtered it intentionally he is liable to receive the death penalty, here, in a case where he slaughtered the animal unwittingly, his slaughter is valid.
9The Gemara challenges: And let us interpret the mishna in accordance with the opinion of Rabbi Yoḥanan HaSandlar, who says: It is no different whether he cooked unwittingly and it is no different whether he cooked intentionally; he may not eat it on Shabbat. The Gemara explains: Rabbi Yoḥanan HaSandlar draws a distinction with regard to the conclusion of Shabbat, in that he permits eating food cooked on Shabbat for others and not for him, while the tanna of our mishna teaches: His slaughter is valid, without qualification, indicating that with regard to his ruling it is no different for him and it is no different for others.
10§ The tanna taught a baraita before Rav: One who cooks on Shabbat unwittingly may eat the food that he cooked; if he did so intentionally, he may not eat the food that he cooked, and Rav silenced him.
11The Gemara asks: What is the reason that Rav silenced him? If we say it is because Rav holds in accordance with the opinion of Rabbi Yehuda and the tanna taught the baraita in accordance with the opinion of Rabbi Meir, can it be that merely because he holds in accordance with the opinion of Rabbi Yehuda he silences one who teaches a baraita in accordance with the opinion of Rabbi Meir?
12And furthermore, does Rav hold in accordance with the opinion of Rabbi Yehuda? But doesn’t Rav Ḥanan bar Ami say: When Rav issues a ruling to his students, he issues a ruling in accordance with the opinion of Rabbi Meir, and when he teaches in his public lecture delivered on the Festival, he teaches in accordance with the opinion of Rabbi Yehuda, due to his concern that the ignoramuses would treat the prohibition of labor on Shabbat with disdain?
13And if you would say that the tanna taught the baraita before Rav during the public lecture and Rav silenced him so that the ignoramuses would not learn from him, is that to say that everyone attending the public lecture listens to the tanna who is citing the baraita ? There is no need to silence the tanna , because they listen to the disseminator [ amora ], the Sage who repeats what he hears from Rav loudly for the benefit of those attending the lecture, and the amora quoted Rav’s ruling in accordance with the opinion of Rabbi Yehuda.
14Rav Naḥman bar Yitzḥak said: The tanna taught the halakha of one who slaughters before Rav: One who slaughters an animal on Shabbat unwittingly may eat from the slaughtered animal; if he slaughtered it intentionally, he may not eat from the slaughtered animal. Rav said to the tanna : What do you think, that the halakha is in accordance with the opinion of Rabbi Meir? Rabbi Meir deems eating permitted only in the case of one who cooks unwittingly on Shabbat, as even before he cooks the food it is fit to be chewed [ lakhos ], i.e., to be eaten uncooked, in a permitted manner, and therefore it was not set aside from use when Shabbat began. But in the case of one who slaughters an animal, where the meat was not fit to chew, Rabbi Meir does not permit eating it on Shabbat, because it was set aside from use on Shabbat.
15The Gemara asks: But isn’t the mishna addressing the case of one who slaughters an animal, and Rav Huna says that Ḥiyya bar Rav taught in the name of Rav: Consumption of the animal is prohibited for that day, and the members of the company of Sages, i.e., those in the academy, tended to say that this halakha is the opinion of Rabbi Yehuda, from which it may be inferred: But Rabbi Meir permits consumption of the slaughtered animal even on Shabbat, and he is not concerned that the animal was set aside from use when Shabbat began?
16The Gemara answers: When Rabbi Meir permits consumption of the slaughtered animal even on Shabbat,
