27 And to the children of Gershon, of the families of the Levites, out of half the tribe of Manasseh, [they gave] the city of refuge for the slayer, Golan in Bashan and its suburbs; and Beeshterah and its suburbs: two cities; 28 and out of the tribe of Issachar, Kishion and its suburbs, Dabrath and its suburbs, 29 Jarmuth and its suburbs, En-gannim and its suburbs: four cities; 30 and out of the tribe of Asher, Mishal and its suburbs, Abdon and its suburbs, 31 Helkath and its suburbs, and Rehob and its suburbs: four cities; 32 and out of the tribe of Naphtali, the city of refuge for the slayer, Kedesh in Galilee, and its suburbs; and Hammoth-Dor and its suburbs, and Kartan and its suburbs: three cities. 33 All the cities of the Gershonites according to their families were thirteen cities and their suburbs.

Commentary on Joshua 21:9-42
(Read Joshua 21:9-42)
By mixing the Levites with the other tribes, they were made to see that the eyes of all Israel were upon them, and therefore it was their concern to walk so that their ministry might not be blamed. Every tribe had its share of Levites' cities. Thus did God graciously provide for keeping up religion among them, and that they might have the word in all parts of the land. Yet, blessed be God, we have the gospel more diffused amongst us.
