Numbers 1:4

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 Numbers 1:16 and Numbers 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.;
