Numbers 4:47-49

Young's Literal Translation

⁴⁷ from a son of thirty years and upward even unto a son of fifty years, every one who is going in to do the work of the service, even the service of burden in the tent of meeting,

⁴⁸ even their numbered ones are eight thousand and five hundred and eighty;

⁴⁹ by the command of Jehovah hath [one] numbered them, by the hand of Moses, each man by his service, and by his burden, with his numbered ones, as Jehovah hath commanded Moses.
