Numbers 4:23-26

23Register all the men between the ages of 30 and 50 who are qualified to serve at the tent of meeting.

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.
