Numbers 18:8-19

⁸ The Lord gave these further instructions to Aaron: "I myself have put you in charge of all the holy offerings that are brought to me by the people of Israel. I have given all these consecrated offerings to you and your sons as your permanent share. ⁹ You are allotted the portion of the most holy offerings that is not burned on the fire. This portion of all the most holy offerings-including the grain offerings, sin offerings, and guilt offerings-will be most holy, and it belongs to you and your sons. ¹⁰ You must eat it as a most holy offering. All the males may eat of it, and you must treat it as most holy. ¹¹ "All the sacred offerings and special offerings presented to me when the Israelites lift them up before the altar also belong to you. I have given them to you and to your sons and daughters as your permanent share. Any member of your family who is ceremonially clean may eat of these offerings. ¹² "I also give you the harvest gifts brought by the people as offerings to the Lord -the best of the olive oil, new wine, and grain. ¹³ All the first crops of their land that the people present to the Lord belong to you. Any member of your family who is ceremonially clean may eat this food. ¹⁴ "Everything in Israel that is specially set apart for the Lord also belongs to you. ¹⁵ "The firstborn of every mother, whether human or animal, that is offered to the Lord will be yours. But you must always redeem your firstborn sons and the firstborn of ceremonially unclean animals. ¹⁶ Redeem them when they are one month old. The redemption price is five pieces of silver (as measured by the weight of the sanctuary shekel, which equals twenty gerahs). ¹⁷ "However, you may not redeem the firstborn of cattle, sheep, or goats. They are holy and have been set apart for the Lord . Sprinkle their blood on the altar, and burn their fat as a special gift, a pleasing aroma to the Lord . ¹⁸ The meat of these animals will be yours, just like the breast and right thigh that are presented by lifting them up as a special offering before the altar. ¹⁹ Yes, I am giving you all these holy offerings that the people of Israel bring to the Lord . They are for you and your sons and daughters, to be eaten as your permanent share. This is an eternal and unbreakable covenant between the Lord and you, and it also applies to your descendants."
