Exodus 21:7-11

“If a man sells his daughter as a female slave, she is not to go free as the male slaves do. If she is displeasing in the eyes of her master who 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 unfairness to her. If he designates her for his son, he shall deal with her according to the custom of daughters. If he takes to himself another woman, he may not reduce her food, her clothing, or her conjugal rights. If he will not do these three things for her, then she shall go out for nothing, without payment of money.
