Deuteronomy 4:41-43

The Voice

⁴¹ Then Moses designated three cities east of the Jordan ⁴² as places where a person could flee if he or she unintentionally killed someone when there was no grudge between them. By fleeing to one of these cities, a person could be safe from revenge and stay alive. ⁴³ These were the cities: Bezer on the plateau in the wilderness for the Reubenites, Ramoth in Gilead for the Gadites, and Golan in Bashan for the Manassites.
