Numbers 4:46-48

Young's Literal Translation

⁴⁶ All those numbered, whom Moses numbered -- Aaron also, and the princes of Israel -- of the Levites, by their families, and by the house of their fathers,

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;
