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,
"Take a census of all the congregation of the people of Israel, by families, by fathers' houses, according to the number of names, every male, head by head;
from twenty years old and upward, all in Israel who are able to go forth to war, you and Aaron shall number them, company by company.
And there shall be with you a man from each tribe, each man being the head of the house of his fathers.
And these are the names of the men who shall attend you. From Reuben, Eli'zur the son of Shed'eur;
from Simeon, Shelu'mi-el the son of Zurishad'dai;
from Judah, Nahshon the son of Ammin'adab;
from Is'sachar, Nethan'el the son of Zu'ar;
