Deuteronomy 22:22-24

“If a man is found lying with the wife of another man, both of them shall die, the man who lay with the woman, and the woman. So you shall purge the evil from Israel. “If there is a betrothed virgin, and a man meets her in the city and lies with her, then you shall bring them both out to the gate of that city, and you shall stone them to death with stones, the young woman because she did not cry for help though she was in the city, and the man because he violated his neighbor’s wife. So you shall purge the evil from your midst.
