Exodus 21:5

2 If thou shalt buy a Hebrew servant, six years he shall serve: and in the seventh he shall depart free for nothing.

3 If he came in by himself, he shall depart by himself: if he was married, then his wife shall depart with him.

4 If his master hath given him a wife, and she hath borne him sons or daughters; the wife and her children shall be her master's, and he shall depart by himself.

5 And if the servant shall plainly say, I love my master, my wife, and my children; I will not depart free:

6 Then his master shall bring him to the judges; he shall also bring him to the door, or to 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 shall sell his daughter to be a maid-servant, she shall not depart as the men-servants do.

8 If she shall not please her master, who hath betrothed her to himself, then shall he let her be redeemed: to sell her to a strange nation he shall have no power, seeing he hath dealt deceitfully with her.
