Numbers 1:4
Ver. 4. And with you there shall be a man of every tribe,.... Excepting Levi, of which Moses and Aaron were, to assist in taking the account, and to see that it was an exact and perfect one:
everyone head of the house of his fathers; and prince of the tribe he belonged to, as appears from Nu 1:16 and Nu 7:2, where an account is given of the same persons as princes of the tribes that offered at the dedication of the altar, who here assisted in the taking this account; the Targum of Jonathan calls them each a prince, as Prince Elizur, &c.
