Leviticus 19:21

And whosoever lieth carnally with a woman, that is a bondmaid, betrothed to an husband, and not at all redeemed, nor freedom given her; she shall be scourged; they shall not be put to death, because she was not free.

And the priest shall make an atonement for him with the ram of the trespass offering before the LORD for his sin which he hath done: and the sin which he hath done shall be forgiven him.
