Deuteronomy 22:23-24

23 If a damsel that is a virgin be betrothed to an husband, and a man find her in the city, and lie with her;

24 Then you shall bring them both out to the gate of that city, and you shall stone them with stones that they die; the damsel, because she cried not, being in the city; and the man, because he has humbled his neighbor's wife: so you shall put away evil from among you.
