Numbers 4:21 - 4:28
Duties of the Gershonites
21 Then Yahweh spoke to Moses, saying, 22 “Take a census of the sons of Gershon also, by their fathers’ households, by their families; 23 from thirty years and upward to fifty years old, you shall number them; all who enter to perform the duty of performing the service in the tent of meeting. 24 This is the service of the families of the Gershonites, in serving and in carrying: 25 they shall carry the curtains of the tabernacle and the tent of meeting with its covering and the covering of porpoise skin that is on top of it, and the screen for the doorway of the tent of meeting, 26 and the hangings of the court, and the screen for the doorway of the gate of the court which is around the tabernacle and the altar, and their cords and all the equipment for their service; and all that is to be done, they shall perform. 27 All the service of the sons of the Gershonites, in all their loads and in all their service, shall be performed at the command of Aaron and his sons; and you shall assign to them as a responsibility all their loads. 28 This is the service of the families of the sons of the Gershonites in the tent of meeting, and their responsibilities shall be under the direction of Ithamar the son of Aaron the priest.
