and the pillars around the court with their bases, pegs, and cords, with all their equipment and all their accessories. And you shall list by name the objects that they are required to carry.

Matthew Henry Presbyterian @wholebiblehenry

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 was to be done regularly. 1. The Gershonites were charged with all the drapery of the tabernacle, the curtains, and hangings, and the coverings of badgers' skins, Num 4:22-26.

And the pillars of the court round about, and their sockets, and their pins, and their cords, with all their instruments, and with all their service: and by name ye shall reckon the instruments of the charge of their burden. (r) You shall take inventory of all the things, which you commit to their charge.
