Deuteronomy 22:23-24

23“Suppose there is a young woman who is a virgin engaged to a man, and another man finds her in the city and lies with her.

24Then you are to bring them both out to the gate of that city and stone them with stones to death—the young woman because she did not cry out in the town, and the man because he humiliated his neighbor’s wife. So you are to purge the evil from your midst.
