Numbers 35:12-19

12These cities will be places of refuge from any relative who can avenge the death. So anyone accused of murder will not have to die until he has had a trial in front of the community.

13There will be six cities you select as places of refuge,

14three on the east side of the Jordan River and three in Canaan.

15These six cities will be places of refuge for Israelites, foreigners, and strangers among you. Anyone who unintentionally kills another person may flee to these cities.

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.
