A person does not defile [as a corpse] until he dies. Even he is cut up or even if he is about to die, he [still] makes levirate marriage obligatory and exempts from levirate marriage, he feeds [his mother] terumah and disqualifies [his mother] from eating terumah. Similarly in the case of cattle or wild animals, they do not defile until they die. If their heads have been cut off, even though they are moving convulsively, they are unclean, like a lizard's tail, which moves convulsively.

Shmuel says: If one rendered the animal like a shard [gistera] by cutting it in two widthwise, its halakhic status is that of an unslaughtered carcass even though it is still convulsing. Rabbi Elazar says: If the thigh, the hind leg of the animal, was removed and its recess is obvious, it is an unslaughtered carcass and it imparts impurity even if it remains alive. The Gemara asks: What are the circumstances of its recess being obvious? Rava said: It is any situation where the animal is collapsed and even so its hind leg is visibly lacking.We learned in a mishna there (Oholot 1:6) with regard to creeping animals whose carcasses are ritually impure: If their heads were removed, even if they are convulsing, they are impure like the tail of a lizard that was severed that convulses even though it is not alive. The Gemara asks: What is the meaning of the term: Were removed? Reish Lakish said: They were actually removed. Rabbi Asi said that Rabbi Mani said: It is like the separation of the head of the bird burnt offering.

If an avalanche fell on someone, and it is doubtful whether or not he is there, or whether he is alive or dead, or whether he is an Israelite or a non-Jew, they remove the debris from above him [even on Shabbat]. If they find him alive they remove the debris, but if dead they should leave him there [until Shabbat is over].

The Rabbis taught: If a person is buried under a collapsed building, until what point does one check to clarify whether the victim is still alive? Until what point is he allowed to continue clearing the debris? They said: One clears until the victim’s nose. If there is no sign of life, i.e., if he is not breathing, he is certainly dead. And some say: One clears until the victim’s heart to check for a heartbeat. If several people are buried and one checked and found the upper ones under the debris dead, he should not say: The lower ones are likely also already dead, and there is no point in continuing to search. There was an incident where they found the upper ones dead and the lower ones alive.The Gemara comments: Let us say that the dispute between these tanna’im who disagree about checking for signs of life is like the dispute between these tanna’im who disagree about the formation of the fetus. As it was taught in a baraita: From what point is the fetus created? It is from its head, as it is stated: “You are He Who took me [gozi] out of my mother’s womb” (Psalms 71:6), and it says: “Cut off [gozi] your hair, and cast it away” (Jeremiah 7:29). These verses suggest that one is created from the head, the place of the hair. Abba Shaul says: A person is created from his navel, and he sends his roots in every direction until he attains the image of a person. The tanna who says that the presence of life is determined based on the nose holds in accordance with the opinion of the tanna who maintains that the formation of a fetus begins with its head. Likewise, the tanna who says the presence of life is determined based on the heart holds in accordance with the opinion of the one who thinks the formation of a fetus begins with its navel. The Gemara rejects this: Even if you say that the formation of a fetus from the navel is the opinion of Abba Shaul, he may nevertheless require one to check the nose for signs of life. Until now, Abba Shaul spoke there only about formation, saying that everything is created from its middle; however, as for saving a life, even Abba Shaul admits that the main sign of life is in the nose, as it is written: “All in whose nostrils was the breath of the spirit of life” (Genesis 7:22).

One whose garment made of cloth, of leather, of sack or of any other material was strapped around his waist, he is permitted to recite Shema. However, for prayer, one may not recite it until he covers his heart, because in prayer he addresses God directly and he must dress accordingly.

The place of stoning was twice a man’s height. One of the witnesses pushed him by the hips, [so that] he was overturned on his heart. He was then turned on his back. If that caused his death, he had fulfilled [his duty]; but if not, the second witness took a stone and threw it on his chest. If he died thereby, he had done [his duty]; but if not, he [the criminal] was stoned by all Israel, for it is says: “The hand of the witnesses shall be first upon him to put him to death, and afterwards the hand of all the people” (Deut. 17:7). All who are stoned are [afterwards] hanged, according to Rabbi Eliezer. But the sages say: “Only the blasphemer and the idolater are hanged.” A man is hanged with his face towards the spectators, but a woman with her face towards the gallows, according to Rabbi Eliezer. But the sages say: a man is hanged, but not a woman. Rabbi Eliezer said to them: “But did not Shimon ben Shetah hang women at ashkelon?” They said: “[On that occasion] he hanged eighty women, even though two must not be tried on the same day. How is he hanged? The post is sunk into the ground with a [cross-] piece branching off [at the top] and he brings his hands together one over the other and hangs him up [thereby]. R. Jose said: the post is leaned against the wall, and he hangs him up the way butchers do. He is immediately let down. If he is left [hanging] over night, a negative command is thereby transgressed, for it says, “You shall not let his corpse remain all night upon the tree, but you must bury him the same day because a hanged body is a curse against god” (Deut. 21:23). As if to say why was he hanged? because he cursed the name [of god]; and so the name of Heaven [God] is profaned.

They measure the Shabbat limit only with a rope fifty cubits long, neither less nor more. And one should measure only while holding the end of the rope on a level with his heart. If he was measuring and he reached a valley or a wall he spans it and resumes his measuring. If he reached a hill he spans it and resumes his measuring, provided he does not go beyond the Shabbat limit. If he is unable to span it in connection with this Rabbi Dostai ben Yannai stated in the name of Rabbi Meir: “I have heard that they pierce the hills.”

The Gemara asks: But did Rabbi Yoḥanan actually say this, that the court must wait for him to regain his mental capabilities? But didn’t Rav Yehuda say that Shmuel says: If one was attacked by another who slit his throat and severed the two pipes, his trachea and esophagus, or the majority of the two pipes, and the dying man signaled and thereby stated through his gestures: Write a bill of divorce for my wife, then those present should write and give a bill of

divorce to his wife?
