So the priests, and the Levites, and the porters, and the singers, and some of the people, and the Nethinims, and all Israel, dwelt in their cities; and when the seventh month came, the children of Israel were in their cities.
So ... all Israel, dwelt in their cities. The utility of these genealogical registers was thus found in guiding to a knowledge of the cities and localities in each tribe to which every family anciently belonged. This verse is borrowed from Ezra 3:1.
