It also says in Tractate Sanhedrin, chapter 9, on the verse “Judah has become unfaithful, and an abomination was committed in Israel and Jerusalem” (Malachi 2:11): Rav Yehuda said: this is Idol Worship, and as it says “Surely, as a woman betrays her lover, So you have betrayed Me, O house of Israel, declares the LORD” (Jeremiah 3:20). “An abomination was committed in Israel” (Malachi 2:11), this is homosexual intercourse, like it says, “and you shall not lie with a man the like you lie with a woman, it is an abomination” (Leviticus 18:20). “for Judah has profaned the sanctuary of the LORD which He loves” (Malachi 2:11), this is prostitution, as it says “neither shall there be a sodomite of the sons of Israel” (Deuteronomy 23:18). “And he married the daughter of a strange god” (Malachi 2:11), this is one who has relations with a Cutite, as it says “As for the man who does this, may the LORD cut off from the tents of Jacob everyone who awakes and answers” (Malachi 2:12), if he is a wise man he will not have vigilant children nor answering students. And if he is a Cohen, he will not have a son who will bring forth an offering to God. Rabbi Chiya said in the name of Rabbi Aba: anyone who has relations with a Cutite, it is as if he married idol worship, as it says “And he married the daughter of a strange god” (Malachi 2:11).
