Numbers 18:7-19 Therefore you and your sons with you shall keep your priests' office for everything of the altar and inside the veil. And you shall serve. I have given your priest's office as a service of gift. And the stranger that comes near shall be put to death.

MKJV⁽ⁱ⁾ ⁷ Therefore you and your sons with you shall keep your priests' office for everything of the altar and inside the veil. And you shall serve. I have given your priest's office as a service of gift. And the stranger that comes near shall be put to death. ⁸ And Jehovah spoke to Aaron, Behold, I have also given you the charge of My heave offerings of all the holy things of the sons of Israel. I have given them to you for 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 sacrifice of theirs, every food offering of theirs, and every sin offering of theirs, and every trespass offering of theirs, which they shall give Me. These are most holy for you and for your sons. ¹⁰ You shall eat it in the Holy of Holies. Every male shall eat it. It shall be holy to you. ¹¹ And this is yours, the heave offering of their gift, with all the wave offerings of the sons of Israel. I have given them to you and to your sons and to your daughters with you, by a statute forever. Everyone that is clean in your house shall eat it. ¹² All the best of the oil, and all the best of the wine, and of the wheat, the first-fruits of them which they shall offer to Jehovah, I have given them to you. ¹³ The first fruits of all that is in the land, which they shall bring to Jehovah, shall be yours. Everyone that is clean in your house shall eat of it. ¹⁴ Everything devoted in Israel shall be yours. ¹⁵ Everything that opens the womb in all flesh, which they bring to Jehovah, of men or animals, shall be yours. Nevertheless, the first-born of man you shall surely redeem, and the first-born of unclean animals you shall redeem. ¹⁶ And those that are to be redeemed from a month old you shall redeem, according to your judgment for the silver of five shekels, according to the shekel of the sanctuary, which is twenty gerahs. ¹⁷ But the first-born of a cow, or the first-born of a sheep, or the first-born of a goat, you shall not redeem. They are holy. You shall sprinkle their blood upon the altar, and shall burn their fat, an offering made by fire, for a sweet savor to Jehovah. ¹⁸ And their flesh shall be yours, as the wave breast and as the right shoulder are yours. ¹⁹ All the heave offerings of the holy things, which the sons of Israel offer to Jehovah, I have given you and your sons and your daughters with you, by a law forever. It is a covenant of salt forever before Jehovah to you and to your seed with you.
