Leviticus 19:20-22 - Lying With A Slave Woman
20 "When a person has sexual relations with a woman servant who is engaged to another man, but she has not been completely redeemed nor has her freedom been granted to her, there is to be an inquiry, but they won't be put to death, since she has not been freed. 21 The perpetrator is to bring his guilt offering to the LORD at the entrance to the Tent of Meeting that is, a ram as a guilt offering. 22 Then the priest is to make atonement for him with the ram as a guilt offering in the LORD's presence on account of his sin which he has committed, but which will be forgiven him."
