Exodus 21:8-11

8If she is 1displeasing in the eyes of her master 2who designated her for himself, then he shall let her be redeemed. He does not have authority to sell her to a foreign people, because of his 3unfairness to her. 9And if he designates her for his son, he shall deal with her according to the custom of daughters. 10If he takes to himself another woman, he may not reduce her 4food, her clothing, or 5her conjugal rights. 11But if he will not do these three things for her, then she shall go 6free for nothing, without payment of money.
