Exodus 21:5 ASV

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

⁴  If his master give him a wife and she bear 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 unto God, and shall bring him to the door, or unto the door-post; and his master shall bore his ear through with an awl; and he shall serve him for ever.

⁷  And if a man sell his daughter to be a maid-servant, she shall not go out as the men-servants do.
