Deuteronomy 4:41-43 - The Narrative Concerning Cities Of Refuge
41 Moses set aside three cities on the east side of the Jordan. 42 Those who unintentionally killed someone whom they had never hated could flee to one of these cities and save their lives. 43 The cities were Bezer on the desert plateau for the tribe of Reuben, Ramoth in Gilead for the tribe of Gad, and Golan in Bashan for the tribe of Manasseh.
