Leviticus 19:20-22 - Lying With A Slave Woman
20 And whoever lies with a woman with semen, and she is a slave-girl, betrothed to a husband and not at all redeemed, nor freedom given her, there shall be an inquest. They shall not be put to death, because she was not free. 21 And he shall bring his trespass offering to Jehovah, to the door of the tabernacle of the congregation, even a ram for a trespass offering. 22 And the priest shall make an atonement for him with the ram of the trespass offering before Jehovah for his sin which he has done. And the sin which he has done shall be forgiven him.
