27 The descendants of Gershon, another clan within the tribe of Levi, received the following towns with their pasturelands from the half-tribe of Manasseh: Golan in Bashan (a city of refuge for those who accidentally killed someone) and Be-eshterah-two towns. 28 From the tribe of Issachar they received the following towns with their pasturelands: Kishion, Daberath, 29 Jarmuth, and En-gannim-four towns. 30 From the tribe of Asher they received the following towns with their pasturelands: Mishal, Abdon, 31 Helkath, and Rehob-four towns. 32 From the tribe of Naphtali they received the following towns with their pasturelands: Kedesh in Galilee (a city of refuge for those who accidentally killed someone), Hammoth-dor, and Kartan-three towns. 33 So in all, thirteen towns with their pasturelands were allotted to the clan of Gershon.

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.
