1:1-43 The people were numbered to show God's faithfulness in thus increasing the seed of Jacob, that they might be the better trained for the wars 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 were 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.

19. As the Lord commanded Moses, &c.—The numbering of the people was not an act sinful in itself, as Moses did it by divine appointment; but David incurred guilt by doing it without the authority of God. (See on [50]2Sa 24:10).
