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.
8And the LORD spoke to Aaron, Behold, I also have given you the charge of my heave offerings of all the hallowed things of the children of Israel; to you have I given them by reason of the anointing, and to your sons, by an ordinance forever.
