Numbers 18:3-5

New Catholic Bible

³They will attend to your duties and all the duties of the tent, but they must not come near the vessels of the sanctuary or the altar, lest they die and you also die. ⁴They will join you and attend to the duties of the tent of meeting, for every service in the tabernacle. Let no one else approach you.

⁵“You will attend to the duties of the sanctuary and the duties of the altar so that no wrath come upon the people of Israel.
