Joshua 20:8-9

On the east side of the Jordan River, across from Jericho, the following cities were designated: Bezer, in the wilderness plain of the tribe of Reuben; Ramoth in Gilead, in the territory of the tribe of Gad; and Golan in Bashan, in the land of the tribe of Manasseh. These cities were set apart for all the Israelites as well as the foreigners living among them. Anyone who accidentally killed another person could take refuge in one of these cities. In this way, they could escape being killed in revenge prior to standing trial before the local assembly.
