Rabbi Shimon says: It is not necessary to derive which transgressions the goat offering atones for by comparing the verse written concerning it to a different verse. Rather, from its own place, i.e., from the verse about the atonement effected by the goat itself, it can be determined, as it states: “And he shall effect atonement upon the Sanctuary [hakodesh] from the impurities of the children of Israel,” which should be interpreted as saying that it atones for the defiling of anything sacred [kodesh], i.e., the Temple or its sacrificial foods.

§ The Gemara now considers which prohibitions are permitted in times of mortal danger. Rabbi Yoḥanan says in the name of Rabbi Shimon ben Yehotzadak: The Sages who discussed this issue counted the votes of those assembled and concluded in the upper story of the house of Nitza in the city of Lod: With regard to all other transgressions in the Torah, if a person is told: Transgress this prohibition and you will not be killed, he may transgress that prohibition and not be killed, because the preserving of his own life overrides all of the Torah’s prohibitions. This is the halakha concerning all prohibitions except for those of idol worship, forbidden sexual relations, and bloodshed. Concerning those prohibitions, one must allow himself to be killed rather than transgress them.

GEMARA:The Sages taught in a baraita: With regard to a pregnant woman who smelled consecrated meat or pig meat and craved those specific foods, one inserts a thin reed into the juice of that item and places it on her mouth. If her mind become settled with that, it is well. And if not, one feeds her the gravy itself of that forbidden food. If her mind becomes settled with that, it is well. And if not, one feeds her the fat of the forbidden food itself, as there is nohalakhathat stands in the way of saving a life except for the prohibitions against idol worship, and forbidden sexual relationships, and bloodshed.

§ The Gemara relates: It once happened that Rabbi Yishmael, and Rabbi Akiva, and Rabbi Elazar ben Azarya were walking on the road, and Levi HaSadar and Rabbi Yishmael, son of Rabbi Elazar ben Azarya, were walking respectfully behind them, since they were younger and did not walk alongside their teachers. This question was asked before them: From where is it derived that saving a life overrides Shabbat?
