Exodus 21:5 KJV

3If he came in by himself, he shall go out by himself: if he were married, then his wife shall go out with him.

4If his master have given him a wife, and she have born him sons or daughters; the wife and her children shall be her master’s, and he shall go out by himself.

5And 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 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.

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