Exodus 21:7

5But if the servant shall plainly say, ‘I love my master, my wife, and my children. I will not go out free;’

6then his master shall bring him to God, and shall bring him to the door or to the doorpost, and his master shall bore his ear through with an awl, and he shall serve him forever.

7“If a man sells his daughter to be a female servant, she shall not go out as the male servants do.

8If she doesn’t please her master, who has married her to himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, since he has dealt deceitfully with her.

9If he marries her to his son, he shall deal with her as a daughter.
