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.
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 winepress.
and it shall be for Aaron and his sons as their portion for ever from the children of Israel; for it is a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifices of their peace-offerings, even their heave-offering unto Jehovah.
