9 Out of the tribe of the people of Judah and the tribe of the people of Simeon they gave the following cities mentioned by name, 10 which went to the descendants of Aaron, one of the clans of the Kohathites who belonged to the people of Levi; since the lot fell to them first. 11 They gave them Kiriath-arba (Arba being the father of Anak), that is Hebron, in the hill country of Judah, along with the pasturelands around it. 12 But the fields of the city and its villages had been given to Caleb the son of Jephunneh as his possession. 13 And to the descendants of Aaron the priest they gave Hebron, the city of refuge for the manslayer, with its pasturelands, Libnah with its pasturelands, 14 Jattir with its pasturelands, Eshtemoa with its pasturelands, 15 Holon with its pasturelands, Debir with its pasturelands, 16 Ain with its pasturelands, Juttah with its pasturelands, Beth-shemesh with its pasturelands--nine cities out of these two tribes; 17 then out of the tribe of Benjamin, Gibeon with its pasturelands, Geba with its pasturelands, 18 Anathoth with its pasturelands, and Almon with its pasturelands--four cities. 19 The cities of the descendants of Aaron, the priests, were in all thirteen cities with their pasturelands.

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.
