Instead, give them the job of caring for the sacred tent, its furnishings, and the objects used for worship. They will camp around the tent, and whenever you move, they will take it down, carry it to the new camp, and set it up again. Anyone else who tries to go near it must be put to death.
When the camp is ready to be moved, the Kohathites will be responsible for carrying the sacred objects and the furnishings of the sacred tent. But Aaron and his sons must have already covered those things so the Kohathites won't touch them and die.
