9 Out of the tribe of Judah and the tribe of Simeon they gave the following cities mentioned by name, 10 which went to the descendants of Aaron, one of the families of the Ko'hathites who belonged to the Levites; since the lot fell to them first. 11 They gave them Kir'iath-ar'ba (Arba being the father of Anak), that is Hebron, in the hill country of Judah, along with the pasture lands round about it. 12 But the fields of the city and its villages had been given to Caleb the son of Jephun'neh as his possession. 13 And to the descendants of Aaron the priest they gave Hebron, the city of refuge for the slayer, with its pasture lands, Libnah with its pasture lands, 14 Jattir with its pasture lands, Eshtemo'a with its pasture lands, 15 Holon with its pasture lands, Debir with its pasture lands, 16 A'in with its pasture lands, Juttah with its pasture lands, Beth-she'mesh with its pasture lands--nine cities out of these two tribes; 17 then out of the tribe of Benjamin, Gibeon with its pasture lands, Geba with its pasture lands, 18 An'athoth with its pasture lands, and Almon with its pasture lands--four cities. 19 The cities of the descendants of Aaron, the priests, were in all thirteen cities with their pasture lands.

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.
