Numbers 4:16-26
English Standard Version
17The Lord spoke to Moses and Aaron, saying,
18"Let not the tribe of the clans of the Kohathites be destroyed from among the Levites,
19but deal thus with them, that they may live and not die when they come near to the most holy things: Aaron and his sons shall go in and appoint them each to his task and to his burden,
20but they shall not go in to look on the holy things even for a moment, lest they die."
21The Lord spoke to Moses, saying,
22"Take a census of the sons of Gershon also, by their fathers ' houses and by their clans.
23From thirty years old up to fifty years old, you shall list them, all who can come to do duty, to do service in the tent of meeting.
24This is the service of the clans of the Gershonites, in serving and bearing burdens:
25they shall carry the curtains of the tabernacle and the tent of meeting with its covering and the covering of goatskin that is on top of it and the screen for the entrance of the tent of meeting
26and the hangings of the court and the screen for the entrance of the gate of the court that is around the tabernacle and the altar, and their cords and all the equipment for their service. And they shall do all that needs to be done with regard to them.
