TSK · Numbers 10:21

Whenever the tabernacle is to move, the Levites must take it down, and whenever the tabernacle is to be reassembled, the Levites must set it up. Any unauthorized person who approaches it must be killed.

The Numbering of the Kohathites From Kohath came the family of the Amramites, the family of the Izharites, the family of the Hebronites, and the family of the Uzzielites; these were the families of the Kohathites.

“When Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, when the camp is ready to journey, then the Kohathites will come to carry them; but they must not touch any holy thing, or they will die. These are the responsibilities of the Kohathites with the tent of meeting.

But to the Kohathites he gave none, because the service of the holy things, which they carried on their shoulders, was their responsibility.

Then David said,“Only the Levites may carry the ark of God, for the LORD chose them to carry the ark of the LORD and to serve before him perpetually.”
