Numbers 18:2-4

Modern English Version

² Your brothers also of the tribe of Levi, the tribe of your father, bring with you, and let them be joined with you, and minister to you. But you and your sons with you will minister before the tent of witness. ³ They will perform duties for you and for the whole tent; but they will not come near the vessels of the sanctuary or the altar, so that neither they nor you die. ⁴ They will be joined to you and perform the duties of the tent of meeting, for all the service of the tent; no foreigner will come near you.
