Deuteronomy 22:24 (KJV)

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

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 neighbour’s wife: so thou shalt put away evil from among you.

But if a man find a betrothed damsel in the field, and the man force her, and lie with her: then the man only that lay with her shall die:

But unto the damsel thou shalt do nothing; there is in the damsel no sin worthy of death: for as when a man riseth against his neighbour, and slayeth him, even so is this matter:
