Numbers 18:8-14

⁸ And Jehovah spoke to Aaron, And I, behold, I have given thee the charge of my heave-offerings, of all the hallowed things of the children of Israel; to thee have I given them, because of the anointing, and to thy sons by an everlasting statute. ⁹ This shall be thine of the most holy things, [reserved] from the fire: every offering of theirs, of all their oblations, and of all their sin-offerings, and of all their trespass-offerings, which they render unto me, it is most holy for thee and for thy sons. ¹⁰ As most holy shalt thou eat it: every male shall eat it; it shall be holy unto thee. ¹¹ And this shall be thine: the heave-offering of their gift, with all the wave-offerings of the children of Israel; I have given them unto thee, and to thy sons and to thy daughters with thee, by an everlasting statute; every one that is clean in thy house shall eat of it. ¹² All the best of the oil, and all the best of the new wine, and of the wheat, the firstfruits of them which they give to Jehovah, have I given thee. ¹³ The first ripe of everything that is in their land, which they shall bring to Jehovah, shall be thine; every one that is clean in thy house shall eat of it. ¹⁴ Every devoted thing in Israel shall be thine.
