Exodus 21:6

3 If he comes in by himself, he shall go out by himself. If he is married, then his wife shall go out with him.

4 If his master gives him a wife and she bears him sons or daughters, the wife and her children shall be her master`s, and he shall go out by himself.

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 to God, and shall 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 "If a man sells his daughter to be a maid-servant, she shall not go out as the men-servants do.

8 If she doesn`t please her master, who has married her to himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, seeing he has dealt deceitfully with her.

9 If he marries her to his son, he shall deal with her after the manner of daughters.
