Numbers 35:16-22

16“But if any of you uses an iron weapon to kill another person, you are a murderer. Murderers must be put to death.

17If any of you picks up a stone as a weapon and uses it to kill another person, you are a murderer. Murderers must be put to death.

18Or if any of you picks up a piece of wood as a weapon and uses it to kill another person, you are a murderer. Murderers must be put to death.

19The relative who can avenge the death must make sure a murderer is put to death. When he catches up with the murderer, he must kill him.

20If any of you kills someone you hate by shoving him or by deliberately throwing something at him,

21or if you beat your enemy to death with your bare hands, you must be put to death. You are a murderer. The relative who can avenge the death must kill you when he catches up with you, because you are a murderer.

22“But suppose you accidentally kill someone who wasn’t your enemy. Maybe you shoved him or threw something at him but didn’t mean to kill him.
