תנ״ך אויף ויקרא 21:9

If a man is found having intercourse with a woman who is the wife of a man, even both of them shall die—the man who had intercourse with the woman and the woman—and you will eliminate the evil from Yisroel.

If there will be a virgin girl married to a man, and a man encounters her in the city and has intercourse with her,

You are to take them both out to the court of that city and stone them with stones to death, the girl for the fact that she did not scream in the city and the man for the fact that he oppressed the wife of his peer; and you will eliminate the evil within you.
