Numbers 18:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ This shall be yours from the most holy things, reserved from the fire: every offering of theirs that they render to me as a most holy thing, whether grain-offering, sin-offering, or guilt-offering, shall belong to you and your sons. ¹⁰ As a most holy thing you shall eat it; every male may eat it; it shall be holy to you. ¹¹ This also is yours: I have given to you, together with your sons and daughters, as a perpetual due, whatever is set aside from the gifts of all the elevation-offerings of the Israelites; everyone who is clean in your house may eat them.
