John Gill's Bible Commentary Ver. 3. And the children of Israel gave unto the Levites out of their inheritance , etc.] Knowing full well there was such a command, made no objection to their motion, but freely gave them cities out of the portion of inheritance allotted to them; this they did at the commandment of the Lord, and in obedience to it, even gave these cities and suburbs ; after mentioned: this was done by the tribes themselves; as there were a certain number fixed by the commandment of God, they agreed among themselves how many and what cities should be given out of each tribe; and then lots were cast for them by Joshua, what and which cities should be appropriated to their several divisions, as the Kohathites that sprang from Aaron, and the rest of them that did not, and the Gershonites and Merarites, as follows.
Matthew Henry Commentary
Verses 1-8 - The Levites waited till the other tribes were provided for, before the preferred their claim to Joshua. They build their claim upon a very good foundation; not their own merits or services, but the Divin 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; the which preach the gospel should live by the gospel, and should liv comfortably. (Jos 21:9-42)
