Deuteronomy 22:21-24

21then they shall bring out the damsel unto the entrance of her father's house, and the men of her city shall stone her with stones that she die: because she hath wrought infamy in Israel, committing fornication in her father's house; and thou shalt put evil away from thy midst.

22If a man be found lying with a man's wife, they shall both of them die, the man that lay with the woman, and the woman; and thou shalt put away evil from Israel.

23If a damsel, a virgin, be betrothed to some one, and a man find her in the city, and lie with her,

24then ye shall bring them both out unto the gate of that city, and stone them with stones that they die; the damsel, because she cried not, [being] in the city, and the man, because he hath humbled his neighbour's wife; and thou shalt put evil away from thy midst.
