Numbers 18:18-20

New Revised Standard Version, Anglicised

¹⁸ but their flesh shall be yours, just as the breast that is elevated and as the right thigh are yours. ¹⁹ All the holy offerings that the Israelites present to the Lord I have given to you, together with your sons and daughters, as a perpetual due; it is a covenant of salt for ever before the Lord for you and your descendants as well. ²⁰ Then the Lord said to Aaron: You shall have no allotment in their land, nor shall you have any share among them; I am your share and your possession among the Israelites.
