3And they shall keep your charge, and the charge of all the tabernacle: only they shall not come near the vessels of the sanctuary and the altar, that neither they, nor you also, die.
4And they shall be joined to you, and keep the charge of the tabernacle of the congregation, for all the service of the tabernacle: and a stranger shall not come near you.
5And you shall keep the charge of the sanctuary, and the charge of the altar: that there be no wrath any more upon the children of Israel.
6And I, behold, I have taken your brethren the Levites from among the children of Israel; to you they are given as a gift for the LORD, to do the service of the tabernacle of the congregation.
7Therefore you and your sons with you shall keep your priest's office for everything of the altar, and within the veil; and you shall serve: I have given your priest's office to you as a service of gift: and the stranger who comes near shall be put to death.
