Numbers 18:28-30

American Standard Version

²⁸ Thus ye also shall offer a heave-offering unto Jehovah of all your tithes, which ye receive of the children of Israel; and thereof ye shall give Jehovah’s heave-offering to Aaron the priest. ²⁹ Out of all your gifts ye shall offer every heave-offering of Jehovah, of all the ^[a]best thereof, even the hallowed part thereof out of it. ³⁰ Therefore thou shalt say unto them, When ye heave the ^[b]best thereof from it, then it shall be reckoned unto the Levites as the increase of the threshing-floor, and as the increase of the winepress.
