34 To the rest of the Levites-the Merarite families-were given out of the tribe of Zebulun: Jokneam with its pasture lands, Kartah with its pasture lands, 35 Dimnah with its pasture lands, Nahalal with its pasture lands-four towns. 36 Out of the tribe of Reuben: Bezer with its pasture lands, Jahzah with its pasture lands, 37 Kedemoth with its pasture lands, and Mephaath with its pasture lands-four towns. 38 Out of the tribe of Gad: Ramoth in Gilead with its pasture lands, the city of refuge for the slayer, Mahanaim with its pasture lands, 39 Heshbon with its pasture lands, Jazer with its pasture lands-four towns in all. 40 As for the towns of the several Merarite families, that is, the remainder of the families of the Levites, those allotted to them were twelve in all.

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.
