Numbers 18:3-5

Common English Bible

³ They will perform their duties for you and the service for the entire tent. But they will not approach the holy equipment of the sanctuary or the altar, lest both they and you die. ⁴ They will assist you and they will perform the duties of the meeting tent with regard to all the work of the tent. But no outsider may accompany you. ⁵ You will perform the duties of the sanctuary and the altar. Then there will no longer be any anger against the Israelites.
