Numbers 4:23-26

23List all the men between the ages of thirty and fifty who are eligible to serve in the Tabernacle.

24“These Gershonite clans will be responsible for general service and carrying loads.

25They must carry the curtains of the Tabernacle, the Tabernacle itself with its coverings, the outer covering of fine goatskin leather, and the curtain for the Tabernacle entrance.

26They are also to carry the curtains for the courtyard walls that surround the Tabernacle and altar, the curtain across the courtyard entrance, the ropes, and all the equipment related to their use. The Gershonites are responsible for all these items.
