²² “If a man is found lying with a married woman, then both of them shall die, the man who lay with the woman, and the woman; thus you shall purge the evil from Israel. ²³ “If there is a girl who is a virgin engaged to a man, and another man finds her in the city and lies with her, ²⁴ then you shall bring them both out to the gate of that city and you shall stone them to death; the girl, because she did not cry out in the city, and the man, because he has violated his neighbor’s wife. Thus you shall purge the evil from among you.
