Joshua 14:1

The historian, having in the foregoing chapter given an account of the disposal of the countries on the other side Jordan, now comes to tell us what they did with the countries in the land of Canaan. They were not conquered to be left desert, a habitation for dragons, and a court for owls, Isa 34:13. No, the Israelites that had hitherto been closely encamped in a body, and the greatest part of them such as never knew any other way of living, must now disperse themselves to replenish these new conquests. It is said of the earth, God created it not in vain; he formed it to be inhabited, Isa 45:18. Canaan would have been subdued in vain if it had not been inhabited. Yet every man might not go and settle where he pleased, but as there seems to have been in the days of Peleg an orderly and regular division of the habitable earth among the sons of Noah (Gen 10:25, Gen 10:32), so there was now such a division of the land of Canaan among the sons of Jacob. God had given Moses directions how this distribution should be made, and those directions are here punctually observed. See Num 26:53, etc. I. The managers of this great affair were Joshua the chief magistrate, Eleazar the chief priest, and ten princes, one of each of the tribes that were now to have their inheritance, whom God himself had nominated (Num 34:17, etc.
