Numbers 18:8-19

⁸ And the Lord said to Aaron, See, I have given into your care my lifted offerings; even all the holy things of the children of Israel I have given to you and to your sons as your right for ever, because you have been marked with the holy oil. ⁹ This is to be yours of the most holy things, out of the fire offerings; every offering of theirs, every meal offering and sin-offering, and every offering which they make on account of error, is to be most holy for you and your sons. ¹⁰ As most holy things they are to be your food: let every male have them for food; it is to be holy to you. ¹¹ And this is yours: the lifted offering which they give and all the wave offerings of the children of Israel I have given to you and to your sons and to your daughters as your right for ever: everyone in your house who is clean may have them for food. ¹² All the best of the oil and the wine and the grain, the first-fruits of them which they give to the Lord, to you have I given them. ¹³ The earliest produce from their land which they take to the Lord is to be yours; everyone in your house who is clean may have it for his food. ¹⁴ Everything given by oath to the Lord in Israel is to be yours. ¹⁵ The first birth of every living thing which is offered to the Lord, of man or beast, is to be yours; but for the first sons of man payment is to be made, and for the first young of unclean beasts. ¹⁶ Payment is to be made for these when they are a month old, at the value fixed by you, a price of five shekels by the scale of the holy place, that is, twenty gerahs to the shekel. ¹⁷ But no such payment may be made for the first birth of an ox or a sheep or a goat; these are holy: their blood is to be dropped on the altar, and their fat burned for an offering made by fire, a sweet smell to the Lord. ¹⁸ Their flesh is to be yours; like the breast of the wave offering and the right leg, it is to be yours. ¹⁹ All the lifted offerings of the holy things which the children of Israel give to the Lord, I have given to you and to your sons and to your daughters as a right for ever. This is an agreement made with salt before the Lord, to you and to your seed for ever.
