פירוש על דברי הימים א 6:39

And these were their settlements for their palaces in their border, etc. until “for theirs was the lot,” i.e., for the Levites and for the priests. All Israel cast lots [to determine] how much of the land of Israel would go to them and to the priests and to the Levites, and the lot fell to Judah first. That is the meaning of “for theirs was the lot”; they were the first to give them the towns mentioned here.
