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.

Matthew Henry's Commentary on Numbers 4:29-33

Commentary on Numbers 4:21-33

(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.
