Numbers 4:30-32

Young's Literal Translation

³⁰ from a son of thirty years and upward even unto a son of fifty years thou dost number them, every one who is going in to the host, to do the service of the tent of meeting.

³¹ `And this [is] the charge of their burden, of all their service in the tent of meeting; the boards of the tabernacle, and its bars, and its pillars, and its sockets,

³² and the pillars of the court round about, and their sockets, and their pins, and their cords, of all their vessels, and of all their service; and by name ye do number the vessels of the charge of their burden.
