Numbers 18:3-7 ▼

3 They are to perform duties for you and for the whole tent. They must not come near the sanctuary equipment or the altar; otherwise, both they and you will die.

4 They are to join you and guard the tent of meeting, doing all the work at the tent, but no unauthorized person may come near you.

5 “You are to guard the sanctuary and the altar so that wrath may not fall on the Israelites again.

6 Look, I have selected your fellow Levites from the Israelites as a gift for you, assigned by the LORD to work at the tent of meeting.

7 But you and your sons will carry out your priestly responsibilities for everything concerning the altar and for what is inside the curtain, and you will do that work. I am giving you the work of the priesthood as a gift, but an unauthorized person who comes near the sanctuary will be put to death.”
