Joshua 20:1-4

1The LORD also spoke to Joshua, saying,

2Speak to the children of Israel, saying, Appoint for you cities of refuge, of which I spoke to you by the hand of Moses:

3That the slayer that killeth any person unintentionally and unknowingly may flee there: and they shall be your refuge from the avenger of blood.

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