Joshua 20:7-9

So the Israelites chose these cities to be cities of safety: Kedesh in Galilee in the mountains of Naphtali; Shechem in the mountains of Ephraim; Kiriath Arba (also called Hebron) in the mountains of Judah; Bezer on the east side of the Jordan River near Jericho in the desert in the land of Reuben; Ramoth in Gilead in the land of Gad; and Golan in Bashan in the land of Manasseh. Any Israelite or anyone living among them who killed someone accidentally was to be allowed to run to one of these cities of safety. There he would not be killed, before he was judged, by the relative who had the duty of punishing a murderer.
