Deuteronomy 22:22-24

22“If a man is found lying with a woman married to a husband, then both of them shall die—the man that lay with the woman, and the woman; so you shall put away the evil from Israel.

23“If a young woman who is a virgin is betrothed to a husband, and a man finds her in the city and lies with her,

24then 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 out in the city, and the man because he humbled his neighbor’s wife; so you shall put away the evil from among you.
