Leviticus 19:20-22

20A slave girl belongs to a man. Another man must not have sex with her. If he does, he is doing a wrong thing. But the girl is not free. He has not bought her. You must punish them. But you must not kill them because the girl was not free.

21The man must bring a male sheep to the door of the Tent of Meeting. It is an offering to the Lord.

22The priest will sacrifice the gift to the Lord. The sacrifice will atone for the man's sin. Then the Lord will forgive the man.
