Exodus 21:8-10

Living Bible

⁸ If she does not please the man who bought her, then he shall let her be bought back again; but he has no power to sell her to foreigners, since he has wronged her by no longer wanting her after marrying her. ⁹ And if he arranges an engagement between a Hebrew slave girl and his son, then he may no longer treat her as a slave girl, but must treat her as a daughter. ¹⁰ If he himself marries her and then takes another wife, he may not reduce her food or clothing, or fail to sleep with her as his wife.
