Leviticus 19:20-22 - Lying With A Slave Woman
20 And when a man shall lie with a woman with effusion of seed, and she a maid-servant betrothed to a man, and not redeemed by ransoming, and freedom not given to her, there shall be a punishment: they shall not die because she was not free. 21 And he brought his trespass to Jehovah, to the door of the tent of appointment, a ram of trespass. 22 And the priest expiated for him with the ram of the trespass, before Jehovah, for his sin which he sinned; and his sin which he sinned was forgiven to him.
