Halakhah sobre Números 25:8

From the laws of the commandment is that which they, may their memory be blessed, said (Sanhedrin 81a) that zealots would attack one who has sexual intercourse with an Aramean (gentile) publicly in the eyes of ten or more Israelites. And the proof of the thing is the story of Pinchas and Zimri. But the zealot is nonetheless only permitted to attack him at the time of the promiscuous act, and like in the story that happened; as it is stated (Numbers 25:8), "and the woman through her belly." But if he separated [from her], we do not kill him, but [rather] bring him to the court and they administer lashes [upon] him, since he did the act publicly. [If] the zealots did not attack him and the court did not administer lashes [upon] him, we know from the words of tradition that he is [punished] by excision, as it is written (Malachi 2:11-12), "and he who husbands (read here as, who has sexual intercourse with) the daughter of a foreign god. The Lord will excise the man that does it." And a gentile who has sexual relations with an Israelite - if she is a married woman, he is killed over her; but, if not, he is not killed. But a Jew who wantonly has sexual relations with a gentile woman - even [if it is] by way of harlotry - she is nonetheless killed, since a mishap happened to an Israelite through her, like the law of an animal. And this thing is explicit in the Torah, as it is stated (Numbers 31:16-17), "They were the ones that were with the word of Bilaam against the Children of Israel, etc. and any woman that could know a man sexually they killed." [This] and the rest of its details are elucidated in Avodah Zarah and Yevamot and Kiddushin (see Mishneh Torah, Laws of Forbidden Intercourse 2).

To give the foreleg, the jaw and the maw to the priest: That Israel was commanded to give the foreleg, the jaw, and the maw from all pure, slaughtered animals to the priest. And about this was it stated (Deuteronomy 18:3), "This shall be the statute of the priests, etc." The Sages, of blessed memory, already said (Chullin 134b) about the reason for this commandment that it was in the merit of Pinchas, their father - who was zealous on behalf of his God with regard to the matter of Kozbi, and [was prepared to] surrender his life for the sanctification of [God's] name, to kill a prince from a tribe of Israel - that his children, the priests, merited this present from God forever: The foreleg - corresponding to, "and he took a spear" (Numbers 25:7); the jaw - in the merit that he prayed for the anguish of Israel, as it is written, "And Pinchas stood up and prayed" (Psalms 106:30); and the maw - corresponding to, "and the woman into her stomach" (Numbers 25:8). And we learn from this that one who openly sanctifies the name of Heaven - he and his descendants attain merit in this world, aside from his merit which is kept eternally for his soul in the World to Come.
