Numbers 1:17-19

21st Century King James Version

¹⁷ And Moses and Aaron took these men who are expressly named.

¹⁸ And they assembled all the congregation together on the first day of the second month; and they declared their pedigrees according to their families, by the house of their fathers, according to the number of the names, from twenty years old and upward by head count.

¹⁹ As the Lord commanded Moses, so he numbered them in the Wilderness of Sinai.
