Numbers 18:8-20King James Version (KJV)
8 And the Lord spake unto Aaron, Behold, I also have given thee the charge of mine heave offerings of all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever.
9 This shall be thine of the most holy things, reserved from the fire: every oblation of their's, every meat offering of their's, and every sin offering of their's, and every trespass offering of their's which they shall render unto me, shall be most holy for thee and for thy sons.
10 In the most holy place shalt thou eat it; every male shall eat it: it shall be holy unto thee.
11 And this is 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 a statute for ever: 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 wine, and of the wheat, the firstfruits of them which they shall offer unto the Lord, them have I given thee.
13 And whatsoever is first ripe in the land, which they shall bring unto the Lord, shall be thine; every one that is clean in thine house shall eat of it.
14 Every thing devoted in Israel shall be thine.
15 Every thing that openeth the matrix in all flesh, which they bring unto the Lord, whether it be of men or beasts, shall be thine: nevertheless the firstborn of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
16 And those that are to be redeemed from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs.
17 But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire, for a sweet savour unto the Lord.
18 And the flesh of them shall be thine, as the wave breast and as the right shoulder are thine.
19 All the heave offerings of the holy things, which the children of Israel offer unto the Lord, have I given thee, and thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the Lord unto thee and to thy seed with thee.
20 And the Lord spake unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any part among them: I am thy part and thine inheritance among the children of Israel.
