Numbers 18
27 Ref And your heave-offering shall be reckoned unto you, as though it were the grain of the threshing-floor, and as the fulness of the winepress.
28 Ref 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 best thereof, even the hallowed part thereof out of it.
30 Ref Therefore thou shalt say unto them, When ye heave the 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 wine-press.
