Joshua 21:4

4.And the lot came out for the families, etc Here is first described the number of cities of which we shall have to speak by and bye. Secondly, it is distinctly said that the lot fell out to the children of Aaron in the tribe of Judah. This did not happen fortuitously, because God in his admirable counsel placed them in that locality where he had determined to choose a temple for himself. Thirdly, the narrative proceeds to give the exact names of the cities, of which the first mentioned is Hebron, of which Caleb, with great equanimity, allowed himself to be deprived. Should any one object that the first city of all that ought to have been given them was Jerusalem, where they were to have their future station, it is easy to answer, that moderate sized cities were delivered to them as their condition required. Moreover, Jerusalem was not then subjugated, as it continued under the power of the Jebusites. In short, it would have been absurd to assign a royal seat to priests. And their religion and faith was the better proved by this, that they migrated of their own accord from their native soil to devote their attention to sacred things. For no priest performed the office without becoming a stranger. Their weakness, however, was so far indulged by giving them a grant of neighboring cities, that they might not have the fatigue of a long journey in going to perform their function. Moreover, the giving of thirteen cities for a habitation to one family, and that not very numerous, confirms what I have elsewhere said, that the other tribes possessed very many cities, (175) of which no mention is made; in a short time this will be more certainly confirmed.
