21 Then the Lord spoke to Moses, saying: 22 "Also take a census of the sons of Gershon, by their fathers' house, by their families. 23 From thirty years old and above, even to fifty years old, you shall number them, all who enter to perform the service, to do the work in the tabernacle of meeting. 24 This is the service of the families of the Gershonites, in serving and carrying: 25 They shall carry the curtains of the tabernacle and the tabernacle of meeting with its covering, the covering of badger skins that is on it, the screen for the door of the tabernacle of meeting, 26 the screen for the door of the gate of the court, the hangings of the court which are around the tabernacle and altar, and their cords, all the furnishings for their service and all that is made for these things: so shall they serve. 27 Aaron and his sons shall assign all the service of the sons of the Gershonites, all their tasks and all their service. And you shall appoint to them all their tasks as their duty. 28 This is the service of the families of the sons of Gershon in the tabernacle of meeting. And their duties shall be under the authority of Ithamar the son of Aaron the priest. 29 "As for the sons of Merari, you shall number them by their families and by their fathers' house. 30 From thirty years old and above, even to fifty years old, you shall number them, everyone who enters the service to do the work of the tabernacle of meeting. 31 And this is what they must carry as all their service for the tabernacle of meeting: the boards of the tabernacle, its bars, its pillars, its sockets, 32 and the pillars around the court with their sockets, pegs, and cords, with all their furnishings and all their service; and you shall assign to each man by name the items he must carry. 33 This is the service of the families of the sons of Merari, as all their service for the tabernacle of meeting, under the authority of Ithamar the son of Aaron the priest."

(Read Numbers 4:21-33)
We have here the charge of the other two families of the Levites, which, though not so honourable as the first, yet was necessary, and to be done regularly. All the things were delivered them by name. It intimates the care God takes of his church and every member of it. The death of the saints is represented as the taking down of the tabernacle, 2 Peter 1:14. All shall be raised up in the great day, when these vile bodies shall be made like the glorious body of Jesus Christ, and so shall be for ever with the Lord.
