Numbers 4:29-49

²⁹ As for the Merarites, you shall enroll them by their clans and their ancestral houses; ³⁰ from thirty years old up to fifty years old you shall enroll them, everyone who qualifies to do the work of the tent of meeting. ³¹ This is what they are charged to carry, as the whole of their service in the tent of meeting: the frames of the tabernacle, with its bars, pillars, and bases, ³² and the pillars of the court all around with their bases, pegs, and cords, with all their equipment and all their related service; and you shall assign by name the objects that they are required to carry. ³³ This is the service of the clans of the Merarites, the whole of their service relating to the tent of meeting, under the hand of Ithamar son of Aaron the priest.

³⁴ So Moses and Aaron and the leaders of the congregation enrolled the Kohathites, by their clans and their ancestral houses, ³⁵ from thirty years old up to fifty years old, everyone who qualified for work relating to the tent of meeting; ³⁶ and their enrollment by clans was two thousand seven hundred fifty. ³⁷ This was the enrollment of the clans of the Kohathites, all who served at the tent of meeting, whom Moses and Aaron enrolled according to the commandment of the Lord by Moses. ³⁸ The enrollment of the Gershonites, by their clans and their ancestral houses, ³⁹ from thirty years old up to fifty years old, everyone who qualified for work relating to the tent of meeting- ⁴⁰ their enrollment by their clans and their ancestral houses was two thousand six hundred thirty. ⁴¹ This was the enrollment of the clans of the Gershonites, all who served at the tent of meeting, whom Moses and Aaron enrolled according to the commandment of the Lord. ⁴² The enrollment of the clans of the Merarites, by their clans and their ancestral houses, ⁴³ from thirty years old up to fifty years old, everyone who qualified for work relating to the tent of meeting- ⁴⁴ their enrollment by their clans was three thousand two hundred. ⁴⁵ This is the enrollment of the clans of the Merarites, whom Moses and Aaron enrolled according to the commandment of the Lord by Moses. ⁴⁶ All those who were enrolled of the Levites, whom Moses and Aaron and the leaders of Israel enrolled, by their clans and their ancestral houses, ⁴⁷ from thirty years old up to fifty years old, everyone who qualified to do the work of service and the work of bearing burdens relating to the tent of meeting, ⁴⁸ their enrollment was eight thousand five hundred eighty. ⁴⁹ According to the commandment of the Lord through Moses they were appointed to their several tasks of serving or carrying; thus they were enrolled by him, as the Lord commanded Moses.
