Numbers 4:15

When Aaron and his sons have finished covering the holy objects and all their equipment, as soon as the camp is ready to move, the Kohathites shall come and do the carrying. But they must not touch the holy objects, or they will die. These are the transportation duties of the Kohathites regarding the Tent of Meeting.

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