Numbers 4:24–33

^24–28“The Gershonites by family and clan will serve by carrying heavy loads: the curtains of the Sanctuary and the Tent of Meeting; the covering of the Tent and the outer covering of dolphin skins; the screens for the entrance to the Tent; the cords; and all the equipment used in its ministries. The Gershonites have the job of doing the work connected with these things. All their work of lifting and carrying and moving is to be done under the supervision of Aaron and his sons. Assign them specifically what they are to carry. This is the work of the Gershonite clans at the Tent of Meeting. Ithamar son of Aaron the priest is to supervise their work.

Assign to each man exactly what he is to carry. This is the ministry of the Merarite clans as they work at the Tent of Meeting under the supervision of Ithamar son of Aaron the priest.”
