4 The lot came out for the families of the Ko'hathites. So those Levites who were descendants of Aaron the priest received by lot from the tribes of Judah, Simeon, and Benjamin, thirteen cities.

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.
