Thematic Bible: Names &c of

Then Moses designated three cities on the east side of the Jordan, where a person who accidentally killed someone could flee, if he killed his neighbor without having enmity toward him in the past. He may flee to one of these cities and live: Bezer in the desert plain for the descendants of Reuben, Ramoth in Gilead for the descendants of Gad, and Golan in Bashan for the descendants of Manasseh.

So they set apart Kedesh in Galilee in the hill country of Naphtali, Shechem in the hill country of Ephraim, and Kiriath-arba (also known as Hebron) in the hill country of Judah. East of Jericho beyond the Jordan River, they reserved Bezer in the wilderness on the plain from the tribe of Reuben, Ramoth in Gilead from the tribe of Gad, and Golan in Bashan from the tribe of Manasseh.
