27 And to the Gershonites, one of the clans of the Levites, were given out of the half-tribe of Manasseh, Golan in Bashan with its pasturelands, the city of refuge for the manslayer, and Beeshterah with its pasturelands--two cities; 28 and out of the tribe of Issachar, Kishion with its pasturelands, Daberath with its pasturelands, 29 Jarmuth with its pasturelands, En-gannim with its pasturelands--four cities; 30 and out of the tribe of Asher, Mishal with its pasturelands, Abdon with its pasturelands, 31 Helkath with its pasturelands, and Rehob with its pasturelands--four cities; 32 and out of the tribe of Naphtali, Kedesh in Galilee with its pasturelands, the city of refuge for the manslayer, Hammoth-dor with its pasturelands, and Kartan with its pasturelands--three cities. 33 The cities of the several clans of the Gershonites were in all thirteen cities with their pasturelands.

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.
