Exodus 21:7-11

7Perhaps a man may sell his daughter to someone as a slave. She is not free to leave her master after six years, as the male slaves are.

8Her master has chosen her for himself. If she does not make her master happy, he must let her family buy her back from him. He cannot sell her to a foreign person. He has not done what he promised to her.

9If the master had chosen the girl to marry his son, he must take care of her like his own daughter.

10If the master marries another woman as well, he must still take care of the first woman. He must continue to give her food and clothes. He must not refuse to sleep with her.

11If he does not do these three things, she may leave him. She does not have to pay him any money.
