4:21-33 We have here the charge of the other two families of the Levites, which, though not so honourable as the first, yet was necessary, and to be done regularly.

throughout the houses of their fathers, by their families; all in their several houses, and in the several families in those houses, that were of the age next mentioned, were to be numbered.
