Joshua 15:20

20.This is the inheritance, etc He had formerly, indeed, traced out the boundaries of the children of Judah; but it is now shown for a different reason how large and fertile the territory was which the Lord in his great liberality had bestowed upon them. One hundred and thirteen cities with their towns and villages are enumerated. The number attests not only the populousness, but also the fertility of the country. And there cannot be a doubt that by the divine blessing a new degree of fertility was imparted to it. The goodness of God was, however, manifested in the very nature of the land selected for his people, a land abounding in all kinds of advantages. If we attend to the number of souls in the tribe, we shall find that one half of the country would have been amply sufficient for their habitation. For when eight hundred were allocated in each of the cities, the remainder had the towns and the villages. It is no doubt true that a portion was afterwards withdrawn and given to the tribe of Simeon. For in this was accomplished the dispersion of which Jacob had prophesied,

“I will divide them in Jacob, and scatter them in Israel.”
(Genesis 49:7)

They were accordingly admitted by the children of Judah as a kind of guests.
