Leviticus 19:20-22 - Lying With A Slave Woman
20 And whosoever lieth carnally with a woman, that is a bondmaid, betrothed to a husband, and not at all redeemed, nor freedom given her; they shall be punished; they shall not be put to death, because she was not free. 21 And he shall bring his trespass-offering unto Jehovah, unto the door of the tent of meeting, even a ram for a trespass-offering. 22 And the priest shall make atonement for him with the ram of the trespass-offering before Jehovah for his sin which he hath sinned: and the sin which he hath sinned shall be forgiven him.
