Exodus 21:2-6

2“If you buy 1a Hebrew slave, he shall serve for six years; but on the seventh he shall go out as a free man without payment. 3If he comes 2alone, he shall go out 3alone; 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 4alone. 5But 5if 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 6God, 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.
