Numbers 18:10-19

10You are to eat it as a most holy offering. Every male may eat it; it is to be holy to you.

11“The contribution of their gifts also belongs to you. I have given all the Israelites’ presentation offerings to you and to your sons and daughters as a permanent statute. Every ceremonially clean person in your house may eat it.

12I am giving you all the best of the fresh oil, new wine, and grain, which the Israelites give to the Lord as their firstfruits.

13The firstfruits of all that is in their land, which they bring to the Lord, belong to you. Every clean person in your house may eat them.

14“Everything in Israel that is permanently dedicated to the Lord belongs to you.

15The firstborn of every living thing, human or animal, presented to the Lord belongs to you. But you must certainly redeem a human firstborn, and redeem the firstborn of an unclean animal.

16You will pay the redemption price for a month-old male according to your assessment: five shekels of silver by the standard sanctuary shekel, which is twenty gerahs.

17“However, you must not redeem the firstborn of an ox, a sheep, or a goat; they are holy. You are to splatter their blood on the altar and burn their fat as a food offering for a pleasing aroma to the Lord.

18But their meat belongs to you. It belongs to you like the breast of the presentation offering and the right thigh.

19“I give to you and to your sons and daughters all the holy contributions that the Israelites present to the Lord as a permanent statute. It is a permanent covenant of salt before the Lord for you as well as your offspring.”
