The Burden of the Sons of Kohath — Numbers 4:13–15

And they shall take away the ashes from the altar, and spread a purple cloth thereon: and they shall put upon it all the vessels thereof, wherewith they minister about it, the firepans, the flesh-hooks, and the shovels, and the basins, all the vessels of the altar; and they shall spread upon it a covering of sealskin, and put in the staves thereof.

And when Aaron and his sons have made an end of covering the sanctuary, and all the furniture of the sanctuary, as the camp is set forward; after that, the sons of Kohath shall come to bear it: but they shall not touch the sanctuary, lest they die. These things are the burden of the sons of Kohath in the tent of meeting.
