Exodus 21:4-6

Young's Literal Translation

⁴ if his lord give to him a wife, and she hath borne to him sons or daughters -- the wife and her children are her lord's, and he goeth out by himself.

⁵ `And if the servant really say: I have loved my lord, my wife, and my sons -- I do not go out free;

⁶ then hath his lord brought him nigh unto God, and hath brought him nigh unto the door, or unto the side-post, and his lord hath bored his ear with an awl, and he hath served him -- to the age.
