Thirteen cities with their suburbs - At the time mentioned here certainly thirteen cities were too large a proportion for the priests, as they and their families amounted to a very small number: but this ample provision was made in reference to their great increase in after times, when they formed twenty-four courses, as in the days of David.
All the cities of the children of Aaron, the priests,.... Those of the Kohathites that came from him:
were thirteen cities with their suburbs; and just so many are mentioned by name in Joshua 21:11.
