Numbers 18:3-5

International Standard Version

³ They are to take care of your concerns and all the responsibilities involved with the tent. But they’re not to approach the holy vessels or the altar. That way, neither you nor they will die. ⁴ They are to join you to maintain services related to the Tent of Meeting, for all the responsibilities involved with the tent. But no unauthorized person^[a] is to approach you. ⁵ Take care of the sanctuary and the services of the altar so that there won’t be any more wrath on the Israelis.
