Exodus 21:6 WEB

⁴  If his master gives him a wife and she bears him sons or daughters, the wife and her children shall be her master's, and he shall go out by himself.

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

⁶  then his master shall bring him to God, and shall bring him to the door or to the door-post, and his master shall bore his ear through with an awl, and he shall serve him for ever.

⁷  'If a man sells his daughter to be a maid-servant, she shall not go out as the men-servants do.

⁸  If 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, seeing he has dealt deceitfully with her.
