Numbers 18:27-32

²⁷that it be areckoned to you into the offering of the first fruits, as well of the cornfloors, as of the presses; (so that it shall be counted for you as though it be an offering of the first fruits, yea, from the threshing floor, and from the winepress;)

²⁸and of all things of which ye take tithes, offer ye the first fruits to the Lord, and give ye those to Aaron, the priest.

²⁹All (the) things which ye shall offer of (the) tithes, and shall separate into the gifts of the Lord (or and shall set apart for a gift to the Lord), shall be the best, and all the choice things.

³⁰And thou shalt say to them, If ye offer to the Lord all the more clean and better things of tithes, it shall be areckoned to you, as if ye gave the first fruits of the cornfloor, and of the press. (And thou shalt say to them, When ye have offered to the Lord all the more clean and better things of the tithes, it shall be counted for you, like the first fruits from the threshing floor, and from the winepress.)

³¹And ye shall eat those tithes in all your places, as well ye as your families, for it is the price for the service, for which ye serve in the tabernacle of witnessing. (And ye shall eat those tithes in all your dwelling places, ye as well as your families, or your households, for it is the payment for the service which ye do, in the Tabernacle of the Witnessing.)

³²And ye shall not do sin on this thing, and reserve the noble things and the fat to you, lest ye defoul the offerings of the sons of Israel, and ye die. (And ye shall not do sin with these things, and take the noble and the fat things for yourselves, lest ye defile the offerings of the Israelites, for then ye shall die or for then ye must be put to death.)
