Numbers 4:21–32

²¹The Lord spoke to Moses, saying, ²²“Take a census of the sons of Gershon also, by their fathers’ houses and by their clans. ^23uFrom thirty years old up to fifty years old, you shall list them, all who can ^vcome to do duty, to do service in the tent of meeting. ²⁴This is the service of the clans of the Gershonites, in serving and bearing burdens: ^25wthey shall carry ^xthe curtains of the tabernacle and the tent of meeting with ^yits covering and the covering of goatskin that is on top of it and the screen for the entrance of the tent of meeting ²⁶and the hangings of the court and the screen for the entrance of the gate of the court that is around the tabernacle and the altar, and their cords and all the equipment for their service. And they shall do all that needs to be done with regard to them. ²⁷All the service of the sons of the Gershonites shall be at the command of Aaron and his sons, in all that they are to carry and in all that they have to do. And you shall assign to their charge all that they are to carry. ²⁸This is the service of the clans of the sons of the Gershonites in the tent of meeting, and their guard duty is to be ^zunder the direction of Ithamar the son of Aaron the priest.

²⁹“As for the sons of Merari, you shall list them by their clans and their fathers’ houses. ^30uFrom thirty years old up to fifty years old, you shall list them, everyone who can come on duty, to do the service of the tent of meeting. ³¹And ^athis 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, ³²and the pillars around the court with their bases, pegs, and cords, with all their equipment and all their accessories. And you shall ^blist by name the objects that they are required to carry.
