Exodus 21:8

5 And 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 unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall serve him for ever.

7 And if a man sell his daughter to be a maidservant, she shall not go out as the menservants do.

8 If she please not her master, who hath betrothed her to himself, then shall he let her be redeemed: to sell her unto a strange nation he shall have no power, seeing he hath dealt deceitfully with her.

9 And if he have betrothed her unto his son, he shall deal with her after the manner of daughters.

10 If he take him another wife; her food, her raiment, and her duty of marriage, shall he not diminish.

11 And if he do not these three unto her, then shall she go out free without money.
