Numbers 1

¹ And Jehovah spoke to Moses in the wilderness of Sinai, in the tabernacle of the congregation on the first of the second month, in the second year after they had gone out of the land of Egypt, saying,

² Lift the heads of all the congregation of the sons of Israel, by their families, by their fathers' houses, according to the number of names, every male, by their heads;

³ from a son of twenty years and upward, all that are able to go forth to war in Israel. You and Aaron shall number them by their armies.
