John Gill's Bible Commentary Ver. 4. And with you there shall be a man of every tribe , etc.] 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, etc.
Matthew Henry Commentary
Verses 1-43 - The people were numbered to show God's faithfulness in thus increasin the seed of Jacob, that they might be the better trained for the war and conquest of Canaan, and to ascertain their families in order to the division of the land. It is said of each tribe, that those wer numbered who were able to go forth to war; they had wars before them though now they met with no opposition. Let the believer be prepared to withstand the enemies of his soul, though all may appear to be peace.
