“Aaron and his sons are to finish covering the holy objects and all their equipment whenever the camp is to move on. The Kohathites will come and carry them, but they are not to touch the holy objects or they will die. These are the transportation duties of the Kohathites regarding the tent of meeting.

So you shall attend to the duties of the sanctuary and the duties of the altar [of burnt offering and the altar of incense], so that there will no longer be wrath on the Israelites [as with Korah, Dathan, and Abiram].

I myself have chosen your brothers the Levites from among the Israelites. They are given to you as a gift from the Lord, to perform the duties of the tent of meeting.
