11 The Lord spoke to Moses in the wilderness of Sinai, in the tent of meeting, on the first day of the second month, in the second year after they had come out of the land of Egypt, saying: 2 Take a census of the whole congregation of Israelites, in their clans, by ancestral houses, according to the number of names, every male individually; 3 from twenty years old and upward, everyone in Israel able to go to war. You and Aaron shall enroll them, company by company. 4 A man from each tribe shall be with you, each man the head of his ancestral house. 5 These are the names of the men who shall assist you: From Reuben, Elizur son of Shedeur. 6 From Simeon, Shelumiel son of Zurishaddai. 7 From Judah, Nahshon son of Amminadab. 8 From Issachar, Nethanel son of Zuar. 9 From Zebulun, Eliab son of Helon. 10 From the sons of Joseph: from Ephraim, Elishama son of Ammihud; from Manasseh, Gamaliel son of Pedahzur. 11 From Benjamin, Abidan son of Gideoni. 12 From Dan, Ahiezer son of Ammishaddai. 13 From Asher, Pagiel son of Ochran. 14 From Gad, Eliasaph son of Deuel. 15 From Naphtali, Ahira son of Enan. 16 These were the ones chosen from the congregation, the leaders of their ancestral tribes, the heads of the divisions of Israel.
17 Moses and Aaron took these men who had been designated by name, 18 and on the first day of the second month they assembled the whole congregation together. They registered themselves in their clans, by their ancestral houses, according to the number of names from twenty years old and upward, individually, 19 as the Lord commanded Moses. So he enrolled them in the wilderness of Sinai.

Commentary on Numbers 1:1-43
(Read Numbers 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.
