Numbers 18:29-31

New Revised Standard Version, Anglicised

²⁹ Out of all the gifts to you, you shall set apart every offering due to the Lord; the best of all of them is the part to be consecrated. ³⁰ Say also to them: When you have set apart the best of it, then the rest shall be reckoned to the Levites as produce of the threshing-floor, and as produce of the wine press. ³¹ You may eat it in any place, you and your households; for it is your payment for your service in the tent of meeting.
