1Here, where the baraita teaches that if one is unsure about the burglar’s intentions it is prohibited for him to kill him, it is referring to a father who comes to rob his son. A father has great compassion for his son, and therefore it may be presumed that he will not kill his son if he resists. Accordingly, the son is prohibited from killing his father unless he knows for certain that his father has the intention of killing him. There, where the baraita teaches that if one is unsure about the burglar’s intentions it is permitted for him to kill him, it is referring to a son who comes to rob his father. Since a son has less compassion for his father, it may be presumed that he would be ready to kill his father if he resists. Therefore, the father is permitted to kill his son unless he knows for certain that his son would never kill him.
2Rav says: With regard to anyone who breaks into my house, I would kill him, as I would presume that he is ready to kill me, except for Rav Ḥanina bar Sheila, whom I would not kill. The Gemara asks: What is the reason that Rav excludes Rabbi Ḥanina bar Sheila? If we say that Rav trusts him because he is a righteous person, this is difficult, as the case is one where he broke into his house, which indicates that he is not a righteous person. Rather, it is because he would say: I am certain that he would have mercy upon me just like a father would have mercy on a son.
3§ The Sages taught in a baraita : “If the sun is risen upon him, there shall be blood shed on his account” (Exodus 22:2), both during the week and on Shabbat. “If a burglar is found breaking in…there shall not be blood shed on his account” (Exodus 22:1), both during the week and on Shabbat.
4The Gemara clarifies this baraita : Granted that with regard to “there shall not be blood shed on his account,” it was necessary to say that this applies both during the week and on Shabbat, as it might enter your mind to say that this is just as it is in the case of those who are executed by the court, who are not executed on Shabbat. Therefore, the baraita teaches us that the burglar may be slain in self-defense even on Shabbat. But with regard to “there shall be blood shed on his account,” the statement that this applies both during the week and on Shabbat is puzzling. Now, if on a weekday he may not be slain, is it necessary to say that he may not be slain on Shabbat?
5Rav Sheshet says: This ruling is necessary only to teach that if a building collapsed on the burglar on Shabbat, one is obligated to clear the pile of stones from on top of him and perform any action necessary to rescue him, even if it involves the desecration of Shabbat; one does not say that while he is not permitted to actively kill him, he is also not obligated to save him.
6§ Concerning the verse that states: “If a burglar is found breaking in, and is smitten and dies, there shall not be blood shed on his account” (Exodus 22:1), the Sages taught a baraita : “And is smitten,” by any person who strikes him; “and dies,” by any means of death by which you can put him to death. The Gemara clarifies this baraita : Granted, with regard to the words “and is smitten,” it was necessary to say that he may be struck by any person, as it might enter your mind to say that it is only the owner of the house whom the burglar is certain will resist him, because there is a presumption that a person does not restrain himself when faced with losing his money, and therefore it is only the homeowner’s life that is in danger from the burglar. But as for another person, the burglar is not sure that he will try to stop him, and therefore that other person may not kill him, since the burglar did not come with the intention of killing him.
7Therefore, the baraita teaches us that this burglar is considered a pursuer, and he is subject to the same halakha as anyone who pursues another in order to kill him, namely, that anyone may kill the pursuer in order to rescue the one being pursued. Therefore, even another person is permitted to kill the burglar in order to save the homeowner. But that which the baraita teaches, that the words “and dies” teach that he may be slain by any means of death by which you can put him to death, why do I need this?
8The Gemara clarifies the difficulty: This can be derived from the halakha governing a murderer, as it is taught in a baraita : The verse with regard to a murderer states: “He that smote him shall be put to death, for he is a murderer” (Numbers 35:21). I have derived only that the murderer is put to death with the mode of execution stated concerning him, namely, killing by decapitation. From where do I derive that if you cannot put him to death with the mode of execution written concerning him, e.g., if he is escaping, that you can put him to death with any mode of execution with which you can put him to death? The verse states: “He that smote him shall be put to death [ mot yumat ],” the doubled verb teaching that he is put to death in any case, by any mode of execution. Why not derive the halakha of a burglar from the halakha of a murderer?
9The Gemara rejects this reasoning: There it is different, as the verse explicitly states: “ Mot yumat ,” which serves to include all modes of execution.
10The Gemara asks: But why not learn from it a principle that can be applied to all people who may be put to death? The Gemara rejects this reasoning: This case does not serve as a source for a principle, because the halakhot of a murderer and of a blood redeemer, i.e., a relative of one who was killed who is allowed to kill his relative’s killer (see Makkot 11b), are two verses that come as one, and two verses that come as one do not teach a principle. In other words, if a halakha is stated with regard to two specific cases in the Torah, the halakha is understood to apply only to those cases. Had the halakha applied to all other relevant cases as well, it would not have been necessary for the Torah to teach it twice. Therefore, the baraita had to teach us that this halakha also applies to a burglar who breaks into a person’s house.
11§ The Sages taught in a baraita : From the words: “If a burglar is found breaking in” (Exodus 22:1), I have derived only that this halakha applies to a burglar who came breaking in through a wall. But from where do I derive that the same halakha applies if he was found on his roof, in his yard, or in the enclosed area behind his house? Therefore, the verse states: “If a burglar is found,” which teaches that the halakha applies in any case. If that is so, what is the meaning when the verse states: “Breaking in”? Because the Torah speaks of a common case, and most thieves are found breaking in.
12It is taught in another baraita : From the words: “If a burglar is found breaking in,” I have derived only that this halakha applies to a burglar who came breaking in through a wall. But from where do I derive that the same halakha applies if he was found on his roof, in his yard, or in the enclosed area behind his house? Therefore, the verse states: “If a burglar is found,” which teaches that the halakha applies in any case. If that is so, what is the meaning when the verse states: “Breaking in”? This teaches that his breaking in is his forewarning. If a burglar is found breaking into a house, the owner need not formally forewarn him before killing him. If he is found elsewhere, such a forewarning is necessary.
13§ Rav Huna says: If a minor was pursuing another person in order to kill him, the pursued party may be saved with the pursuer’s life. That is to say, one is permitted to save the pursued party by killing the minor who is pursuing him, and one does not say that since the minor lacks halakhic competence, he is not subject to punishment. The Gemara explains: Rav Huna maintains that a pursuer, in general, does not require forewarning, and there is no difference with regard to this matter between an adult and a minor. The essence of the matter is rescuing the pursued party from death, and therefore the pursuer’s liability to receive the death penalty is irrelevant.
14Rav Ḥisda raised an objection to Rav Huna from a baraita : If a woman was giving birth and her life was being endangered by the fetus, the life of the fetus may be sacrificed in order to save the mother. But once his head has emerged during the birthing process, he may not be harmed in order to save the mother, because one life may not be pushed aside to save another life. If one is permitted to save the pursued party by killing the minor who is pursuing him, why is this so? The fetus is a pursuer who is endangering his mother’s life. The Gemara answers: This is not difficult, as it is different there, with regard to the woman giving birth, since she is being pursued by Heaven. Since the fetus is not acting of his own volition and endangering his mother of his own will, his life may not be taken in order to save his mother.
15The Gemara suggests: Let us say that a baraita supports the ruling of Rav Huna, who said that a pursuer does not require a forewarning: If a pursuer was pursuing another person in order to kill him, a third party says to the pursuer: See that he whom you are pursuing to kill is a Jew, and a loyal member of the covenant, and the Torah stated: “Whoever sheds the blood of man, by man shall his blood be shed” (Genesis 9:6). The Torah stated: Save the blood of this person who is being pursued with the blood of that person who is pursuing him. The fact that there is no indication here that the pursuer must say that he heard the forewarning suggests that forewarning is not required, as stated by Rav Huna.
16The Gemara rejects this suggestion: Perhaps this baraita was taught in accordance with the opinion of Rabbi Yosei, son of Rabbi Yehuda. As it is taught in a baraita : Rabbi Yosei, son of Rabbi Yehuda, says: A ḥaver , who is thoroughly knowledgeable in halakha , does not need to be issued a forewarning by witnesses in order to become liable to be punished, because forewarning is given only to distinguish between unintentional sin and intentional sin, and a ḥaver is certainly aware of the halakha . The same may be said about a pursuer: Since his malice is clear, he does not require a forewarning; his sin is obviously intentional. Those who disagree with Rabbi Yosei, son of Rabbi Yehuda, and say that even a ḥaver needs to be issued a forewarning would say that a pursuer must be forewarned as well.
17The Gemara suggests: Come and hear a proof that a pursuer must be forewarned, and therefore one may not save a pursued party by killing a minor who is pursuing him, from a baraita : If a pursuer was pursuing another person in order to kill him, and a third party said to him: See that he whom you are pursuing to kill is a Jew, and a loyal member of the covenant, and the Torah stated: “Whoever sheds the blood of man, by man shall his blood be shed” (Genesis 9:6), in this case, if the pursuer said: I know this to be so, he is exempt from being killed, but if he said: I am doing it on this condition, i.e., knowing that I am liable to be killed for this, he is liable to be slain. This indicates that even a pursuer must be issued a forewarning.
18The Gemara rejects this proof: This forewarning is not necessary except in a case where the pursuer and the person issuing the warning are standing on two opposite sides of a river, so that the latter cannot save the party being pursued by killing the pursuer. What is there for him to do? Unable to save the pursued party, he wants at least to bring the pursuer to court, so that he will be convicted and have the death penalty administered to him. But in order to administer punishment, the court requires that the offender receive proper forewarning. It is for this reason that the baraita speaks of forewarning, but a pursuer may be killed by a bystander even without having been forewarned.
19If you wish, say instead that Rav Huna could have said to you: I stated my opinion that it is permitted to kill a minor pursuer in accordance with the tanna who spoke of the issue of a burglar who breaks into a house. As this tanna says that his breaking in is his forewarning, that is, a burglar who breaks into a house needs no further forewarning. Here, too, anyone who is pursuing another in order to kill him does not require forewarning since his pursuit is his forewarning.
