Deuteronomy 22
22 Ref If a man be found lying with a woman married to an husband, then they shall both of them die, both the man that lay with the woman, and the woman: so shalt thou put away evil from Israel.
23 Ref If a damsel that is a virgin be betrothed unto an husband, and a man find her in the city, and lie with her;
24 Ref Then ye shall bring them both out unto the gate of that city, and ye shall 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 neighbor's wife: so thou shalt put away evil from among you.
