Exodus 21:6-8

New Revised Standard Version, Anglicised

⁶ then his master shall bring him before God.^[a] He shall be brought to the door or the doorpost; and his master shall pierce his ear with an awl; and he shall serve him for life.

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.
