Exodus 21:9

5 But if the servant declares, ‘I love my master and my wife and children; I do not want to go free,’

6 then his master is to bring him before the judges. And he shall take him to the door or doorpost and pierce his ear with an awl. Then he shall serve his master for life.

7 And if a man sells his daughter as a servant, she is not to go free as the menservants do.

8 If she is displeasing in the eyes of her master who had designated her for himself, he must allow her to be redeemed. He has no right to sell her to foreigners, since he has broken faith with her.

9 And if he chooses her for his son, he must deal with her as with a daughter.

10 If he takes another wife, he must not reduce the food, clothing, or marital rights of his first wife.

11 If, however, he does not provide her with these three things, she is free to go without monetary payment.

12 Whoever strikes and kills a man must surely be put to death.

13 If, however, he did not lie in wait, but God allowed it to happen, then I will appoint for you a place where he may flee.
