Exodus 21:6-8

Common English Bible

⁶ then his master will bring him before God. He will bring him to the door or the doorpost. There his master will pierce his ear with a pointed tool, and he will serve him as his slave for life.

⁷ When a man sells his daughter as a slave, she shouldn’t be set free in the same way as male slaves are set free. ⁸ If she doesn’t please her master who chose her for himself, then her master must let her be bought back by her family. He has no right to sell her to a foreign people since he has treated her unfairly.
