1all of the brothers should be concerned, lest their death be approaching. Similarly, if one member of a group dies, the entire group should be concerned. Some say the concern is greatest if the eldest dies. If he, despite his virtues, could not avoid punishment, others will certainly not be saved. And some say the concern is greatest if the youngest dies, because the least significant people are punished first, and perhaps this is the start of a punishment for the entire group.
2We learned in the mishna: And anyone who performs labors destructively on Shabbat is exempt. Rabbi Abbahu taught this baraita before Rabbi Yoḥanan: Anyone who performs labors destructively on Shabbat is exempt, except for one who inflicts a wound or kindles a fire. Rabbi Yoḥanan said to him: Go teach that outside. This baraita is not fit for discussion in the study hall. The opinion that deems one liable for inflicting a wound or kindling a fire on Shabbat is not an accepted teaching and should be ignored. And if you want to say that it is a legitimate teaching, one who inflicts a wound would only be liable in a case where he needed the blood to give to his dog, and one who kindles a fire would only be liable in a case where he needs its ashes.
3The Gemara asks: How could Rabbi Abbahu teach this baraita ? Didn’t we learn explicitly in the mishna: Anyone who performs labors destructively on Shabbat is exempt, including one who inflicts a wound or who kindles a fire? The Gemara answers: In his opinion, the mishna is in accordance with the opinion of Rabbi Yehuda, who deems one liable for performing labor which is not needed for its own sake, whereas the baraita is in accordance with the opinion of Rabbi Shimon, who exempts in that case. The Gemara explains: What is the reason that Rabbi Shimon deems one who inflicts a wound or kindles a fire on Shabbat liable even though these are destructive acts? From the fact that a verse was necessary to permit circumcision on Shabbat, by inference, in general, one who inflicts a wound is liable. If inflicting a wound was not prohibited on Shabbat, there would be no need to permit circumcision.
4Similarly, from the fact that the Torah prohibited kindling a fire on Shabbat even with regard to the execution by burning of a priest’s daughter who committed adultery, conclude from it that in general, one who ignites a fire on Shabbat is liable.
5The Gemara asks: And how does Rabbi Yehuda address this proof? The Gemara answers: There, that is a case of a constructive labor in accordance with the explanation of Rav Ashi. For Rav Ashi said: What difference is there to me between repairing the child through circumcision and repairing a vessel? They are both constructive acts. And what difference is there to me between cooking a lead wick, as a melted lead wick was poured down the throat of the criminal sentenced to execution by burning, and cooking herbs used to produce dyes in the Tabernacle? The Torah addressed these cases specifically because they are constructive, and nothing can be derived from them with regard to liability for performance of destructive labors.
6We learned in the mishna: The measure that determines liability for one who whitens and for similar prohibited labors is the full width of a double sit . Rav Yosef would demonstrate the width of a double sit by indicating the distance between the index and middle fingers and instructing the onlookers to double the measure. Rabbi Ḥiyya bar Ami would demonstrate in a simple manner, as he calculated that the distance between the thumb and the forefinger is equal to a double sit .
7MISHNA: Rabbi Yehuda says: One who traps a bird into a closet or cage, and one who traps a deer into a house is liable. The Rabbis say: One is liable for trapping a bird into a closet
