10 and they were for the children of Aaron, of the families of the Kohathites, who were of the children of Levi; for theirs was the first lot. 11 They gave them Kiriath Arba, named after the father of Anak (the same is Hebron), in the hill country of Judah, with its suburbs around it. 12 But they gave the fields of the city and its villages to Caleb the son of Jephunneh for his possession.

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.
