Numbers 35:9-15

GOD spoke to Moses: “Speak to the People of Israel. Tell them, When you cross the River Jordan into the country of Canaan, designate your asylum-cities, towns to which a person who accidentally kills someone can flee for asylum. They will be places of refuge from the avenger so that the alleged murderer won’t be killed until he can appear before the community in court. Provide six asylum-cities. Designate three of the towns to the east side of the Jordan, the other three in Canaan proper—asylum-cities for the People of Israel, for the foreigner, and for any occasional visitors or guests—six asylum-cities to run to for anyone who accidentally kills another.
