Numbers 4:21–32

²¹And Jehovah spoke to Moses, saying, ²²Take also the sum of the sons of Gershon, according to their fathers’ houses, after their families. ²³From thirty years old and upward to fifty years old shalt thou number them; every one that cometh to labour in the work, to perform the service in the tent of meeting. ²⁴This shall be the service of the families of the Gershonites, in serving, and in carrying: ²⁵they shall carry the curtains of the tabernacle, and the tent of meeting, its covering, and the covering of badgers’ skin that is above upon it, and the curtain of the entrance to the tent of meeting, ²⁶and the hangings of the court, and the curtain of the entrance, of the gate of the court, which surroundeth the tabernacle and the altar, and the cords thereof, and all the instruments of their service; and all that is to be done for these things shall they perform. ²⁷At the commandment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their carrying, and in all their service; and ye shall appoint unto them in charge all their carrying. ²⁸This is the service of the families of the sons of Gershon in the tent of meeting, and their charge shall be under the hand of Ithamar the son of Aaron the priest. ²⁹The sons of Merari: after their families, according to their fathers’ houses shalt thou number them; ³⁰from thirty years old and upward even to fifty years old shalt thou number them, every one that entereth into the labour, to perform the service of the tent of meeting. ³¹And this shall be the charge of their burden, according to all their service in the tent of meeting: the boards of the tabernacle, and the bars thereof, and the pillars thereof, and bases thereof, ³²and the pillars of the court round about, and their bases, and their pegs, and their cords, all their instruments, according to all their service; and by name ye shall number to them the materials which are their charge to carry.
