Deuteronomy 22:21-24

21they will bring the woman to the door of her father’s house, and the men of her city will stone her to death. For she has committed an outrage in Israel by being promiscuous while living in her father’s house. You must purge the evil from you.

22“If a man is discovered having sexual relations with another man’s wife, both the man who had sex with the woman and the woman must die. You must purge the evil from Israel.

23If there is a young woman who is a virgin engaged to a man, and another man encounters her in the city and sleeps with her,

24take the two of them out to the gate of that city and stone them to death — the young woman because she did not cry out in the city and the man because he has violated his neighbor’s fiancée. You must purge the evil from you.
