Numbers 35:16-21, 24

“But if someone strikes and kills another person with a piece of iron, it is murder, and the murderer must be executed. Or if someone with a stone in his hand strikes and kills another person, it is murder, and the murderer must be put to death. Or if someone strikes and kills another person with a wooden object, it is murder, and the murderer must be put to death. The victim’s nearest relative is responsible for putting the murderer to death. When they meet, the avenger must put the murderer to death. So if someone hates another person and waits in ambush, then pushes him or throws something at him and he dies, it is murder. Or if someone hates another person and hits him with a fist and he dies, it is murder. In such cases, the avenger must put the murderer to death when they meet.

If this should happen, the community must follow these regulations in making a judgment between the slayer and the avenger, the victim’s nearest relative
