Numbers 35:9-21

9Then the LORD said to Moses, 10“Speak to the Israelites and tell them: When you cross the Jordan into the land of Canaan, 11designate cities to serve as your cities of refuge, so that a person who kills someone unintentionally may flee there. 12You are to have these cities as a refuge from the avenger, so that the manslayer will not die until he stands trial before the assembly.

13The cities you select will be your six cities of refuge. 14Select three cities across the Jordan and three in the land of Canaan as cities of refuge. 15These six cities will serve as a refuge for the Israelites and for the foreigner or stranger among them, so that anyone who kills a person unintentionally may flee there.

16If, however, anyone strikes a person with an iron object and kills him, he is a murderer; the murderer must surely be put to death. 17Or if anyone has in his hand a stone of deadly size, and he strikes and kills another, he is a murderer; the murderer must surely be put to death. 18If anyone has in his hand a deadly object of wood, and he strikes and kills another, he is a murderer; the murderer must surely be put to death.

19The avenger of blood is to put the murderer to death; when he finds him, he is to kill him.

20Likewise, if anyone maliciously pushes another or intentionally throws an object at him and kills him, 21or if in hostility he strikes him with his hand and he dies, the one who struck him must surely be put to death; he is a murderer. When the avenger of blood finds the murderer, he is to kill him.
