Numbers 4:24–33

²⁴“This is what the Gershonite families will do and what they will carry: ²⁵They will carry the sheets that are part of the inner tent and the tent of meeting. They will also carry the inner cover for the tent of meeting, the outer cover of fine leather that goes over it, the screen for the entrance to the tent of meeting, ²⁶the curtains for the courtyard around the tent and the altar, the screen for the entrance to the courtyard, the ropes, and all the equipment used to set up the curtains. The Gershonites will do everything that needs to be done with these things. ²⁷All their work, whatever they carry and all their duties, will be done under the direction of Aaron and his sons. You are in charge of telling them everything they’re supposed to carry. ²⁸This is the work of the Gershonite families in the tent of meeting. Ithamar, son of the priest Aaron, will be in charge of them. 

²⁹“Register the Merarites by families and households. ³⁰Register all the men between the ages of 30 and 50 who are qualified to serve at the tent of meeting. ³¹These are their duties as they work at the tent of meeting: They will carry the framework for the inner tent, the crossbars, posts, and sockets, ³²the posts for the surrounding courtyard, the bases, pegs, and ropes. They must take care of all this equipment. Tell each man by name the things he will carry. ³³This is what the Merarite families will do as they work at the tent of meeting. Ithamar, son of the priest Aaron, will be in charge of them.”
