Joshua 20:1-4

1And Jehovah spoke to Joshua, saying,

2Speak to the children of Israel, saying, Appoint for yourselves the cities of refuge, whereof I spoke unto you through Moses,

3that the slayer who unwittingly without intent smiteth any one mortally may flee thither: and they shall be your refuge from the avenger of blood.

4And he shall flee unto one of those cities and stand at the entrance of the city-gate, and shall declare his matter in the ears of the elders of that city; and they shall take him into the city unto them, and give him a place, that he may dwell among them.
