Deuteronomy 4:41-43 - The Narrative Concerning Cities Of Refuge
41 Then Moses selected three cities in the Transjordan, toward the east. 42 Anyone who accidentally killed someone without hating him at the time of the accident could flee to one of those cities and be safe. 43 These cities are Bezer, in the desert plateau, for the Reubenites; Ramoth in Gilead for the Gadites; and Golan in Bashan for the Manassehites.
