Exodus 21:8-10

The Voice

⁸ If for any reason she does not please her master who handpicked her for a wife, then he is to allow her to be bought by another. He has no right to sell her to a foreign people because he has broken the agreement with her.

⁹ If the master chooses her as a wife for his son, then the master must treat her just as he would his own daughter.

¹⁰ If the master decides he wants to marry an additional wife, then he must not reduce his slave-wife’s food or clothing or any other marital rights.
