Exodus 21:5-7

American Standard Version

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 ^[a]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 ^[b]maid-servant, she shall not go out as the men-servants do.
