1:20 By their generations - That is, the persons begotten of Reuben's immediate children, who are here subdivided into families, and they into houses, and they into particular persons.
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.
