And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto Yahweh.
Thus ye also shall offer an heave offering unto Yahweh of all your tithes, which ye receive of the children of Israel; and ye shall give thereof Yahweh's heave offering to Aaron the priest.
Therefore thou shalt say unto them, When ye have heaved the best thereof from it, then it shall be counted unto the Levites as the increase of the threshingfloor, and as the increase of the winepress.
