27 Also to the children of Gershon, of the families of the Levites, from the other half-tribe of Manasseh, they gave Golan in Bashan with its common-land (a city of refuge for the slayer), and Be Eshterah with its common-land: two cities; 28 and from the tribe of Issachar, Kishion with its common-land, Daberath with its common-land, 29 Jarmuth with its common-land, and En Gannim with its common-land: four cities; 30 and from the tribe of Asher, Mishal with its common-land, Abdon with its common-land, 31 Helkath with its common-land, and Rehob with its common-land: four cities; 32 and from the tribe of Naphtali, Kedesh in Galilee with its common-land (a city of refuge for the slayer), Hammoth Dor with its common-land, and Kartan with its common-land: three cities. 33 All the cities of the Gershonites according to their families were thirteen cities with their common-lands.
Matthew Henry's Commentary on Joshua 21:27-33
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.
