Leviticus 19:20-22

20“If a man has sexual intercourse with a female slave who is engaged to another man and if her freedom was never bought or given to her, they should not be put to death. He will only pay a fine because she is a slave.

21He must bring a ram for his guilt offering to the Lord at the entrance to the tent of meeting.

22In the Lord’s presence the priest will use them to make peace with the Lord for this sin. The man will be forgiven for this sin.
