Deuteronomy 4:41-43

The Narrative Concerning Cities of Refuge

4:41 Then Moses selected three cities in the Transjordan, toward the east. 4:42 Anyone who accidentally killed someone without hating him at the time of the accident could flee to one of those cities and be safe. 4:43 These cities are Bezer, in the desert plateau, for the Reubenites; Ramoth in Gilead for the Gadites; and Golan in Bashan for the Manassehites.

Deuteronomy 19:8-10

19:8 If the Lord your God enlarges your borders as he promised your ancestors and gives you all the land he pledged to them, 19:9 and then you are careful to observe all these commandments I am giving you today (namely, to love the Lord your God and to always walk in his ways), then you must add three more cities to these three. 19:10 You must not shed innocent blood in your land that the Lord your God is giving you as an inheritance, for that would make you guilty.

Joshua 20:7-9

20:7 So they selected Kedesh in Galilee in the hill country of Naphtali, Shechem in the hill country of Ephraim, and Kiriath Arba (that is, Hebron) in the hill country of Judah. 20:8 Beyond the Jordan east of Jericho they selected Bezer in the desert on the plain belonging to the tribe of Reuben, Ramoth in Gilead belonging to the tribe of Gad, and Golan in Bashan belonging to the tribe of Manasseh. 20:9 These were the cities of refuge appointed for all the Israelites and for resident foreigners living among them. Anyone who accidentally killed someone could escape there and not be executed by the avenger of blood, at least until his case was reviewed by the assembly.
