Exodus 21:7-9

7“If a man sells his daughter as a servant, she is not to go free as male servants do. 8If she does not please the master who has selected her for himself, Or master so that he does not choose her he must let her be redeemed. He has no right to sell her to foreigners, because he has broken faith with her. 9If he selects her for his son, he must grant her the rights of a daughter.
