Exodus 21:8-11

8If she does not please her master who has selected her for himself, then he is to allow her to be redeemed. He will have no power to sell her to a foreign people, seeing as he has dealt deceitfully toward her.

9If he betroths her to his son, he must give her the rights of a daughter.

10If he takes another wife, he is not to diminish her food, her clothing, or her marriage rights.

11If he does not provide these three to her, then she is to go free without payment.
