Leviticus 19:20-22

20“‘When a man has sexual intercourse with a woman, although she is a slave woman designated for another man and she has not yet been ransomed, or freedom has not been granted to her, there will be an obligation to pay compensation. They must not be put to death, because she was not free.

21He must bring his guilt offering to the Lord at the entrance of the Meeting Tent, a guilt offering ram,

22and the priest is to make atonement for him with the ram of the guilt offering before the Lord for his sin that he has committed, and he will be forgiven of his sin that he has committed.
