Exodus 21:9-16
English Standard Version
Chapter 21
9If he designates her for his son, he shall deal with her as with a daughter. 10If he takes another wife to himself, he shall not diminish her food, her clothing, or her marital rights. 11And if he does not do these three things for her, she shall go out for nothing, without payment of money.
12"Whoever strikes a man so that he dies shall be put to death.
13But if he did not lie in wait for him, but God let him fall into his hand, then I will appoint for you a place to which he may flee.
14But if a man willfully attacks another to kill him by cunning, you shall take him from my altar, that he may die.
