4 The lot came out for the families of the Kohathites this way: Levites descended from Aaron the priest received by lot thirteen cities out of the tribes of Judah, Simeon, and Benjamin.

Matthew Henry's Commentary on Joshua 21:4

Commentary on Joshua 21:1-8

(Read Joshua 21:1-8)

The Levites waited till the other tribes were provided for, before they preferred their claim to Joshua. They build their claim upon a very good foundation; not their own merits or services, but the Divine precept. The maintenance of ministers is not a thing left merely to the will of the people, that they may let them starve if they please; they which preach the gospel should live by the gospel, and should live comfortably.
