Numbers 18:8-19

⁸ And Jehovah spake unto Aaron, And I, behold, I have given thee the charge of my heave-offerings, even all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, as a portion for ever. ⁹ This shall be thine of the most holy things, [reserved] from the fire: every oblation of theirs, even every meal-offering of theirs, and every sin-offering of theirs, and every trespass-offering of theirs, which they shall render unto me, shall be most holy for thee and for thy sons. ¹⁰ As the most holy things shalt thou eat thereof; every male shall eat thereof: it shall be holy unto thee. ¹¹ And this is thine: the heave-offering of their gift, even 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, as a portion for ever; every one that is clean in thy house shall eat thereof. ¹² All the best of the oil, and all the best of the vintage, and of the grain, the first-fruits of them which they give unto Jehovah, to thee have I given them. ¹³ The first-ripe fruits of all that is in their land, which they bring unto Jehovah, shall be thine; every one that is clean in thy house shall eat thereof. ¹⁴ Everything devoted in Israel shall be thine. ¹⁵ Everything that openeth the womb, of all flesh which they offer unto Jehovah, both of man and beast shall be thine: nevertheless the first-born of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem. ¹⁶ And those that are to be redeemed of them from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary (the same 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 savor unto Jehovah. ¹⁸ And the flesh of them shall be thine, as the wave-breast and as the right thigh, it shall be thine. ¹⁹ All the heave-offerings of the holy things, which the children of Israel offer unto Jehovah, have I given thee, and thy sons and thy daughters with thee, as a portion for ever: it is a covenant of salt for ever before Jehovah unto thee and to thy seed with thee.
