Exodus 21:7-9

New Revised Standard Version, Anglicised

⁷ When a man sells his daughter as a slave, she shall not go out as the male slaves do. ⁸ If she does not please her master, who designated her for himself, then he shall let her be redeemed; he shall have no right to sell her to a foreign people, since he has dealt unfairly with her. ⁹ If he designates her for his son, he shall deal with her as with a daughter.
