Numbers 18:27-30

NHEB(i) 27 Your wave offering shall be reckoned to you, as though it were the grain of the threshing floor, and as the fullness of the winepress. 28 Thus you also shall offer a wave offering to the LORD of all your tithes, which you receive of the children of Israel; and of it you shall give the LORD's wave offering to Aaron the priest. 29 Out of all your gifts you shall offer every wave offering of the LORD, of all its best, even the holy part of it out of it.' 30 "Therefore you shall tell them, 'When you heave its best from it, then it shall be reckoned to the Levites as the increase of the threshing floor, and as the increase of the winepress.
