6 And 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.
7 Therefore 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.
8 And 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.
9 This shall be yours of the most holy things, reserved from the fire: every offering of theirs, every grain offering of theirs, and every sin offering of theirs, and every trespass offering of theirs, which they shall render to me, shall be most holy for you and for your sons.
