Exodus 21:3-6

3If he comes 1alone, he shall go out 2alone; if he is the husband of a wife, then his wife shall go out with him. 4If his master gives him a wife, and she bears him sons or daughters, the wife and her children shall belong to her master, and he shall go out 3alone. 5But 4if the slave plainly says, ‘I love my master, my wife and my children; I will not go out as a free man,’ 6then his master shall bring him to 5God, then he shall bring him to the door or the doorpost. And his master shall pierce his ear with an awl; and he shall serve him permanently.
