27 And to the children of Gershon, of the families of the Levites, they gave from the half-tribe of Manasseh, Golan in Bashan with its grass-lands, the town where the taker of life might be safe, and Ashtaroth with its grass-lands, two towns.

Matthew Henry's Commentary on Joshua 21:27

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.
