and it shall be for Aharon and his sons as their portion forever from the children of Yisra'el; for it is a wave offering: and it shall be a wave offering from the children of Yisra'el of the sacrifices of their shalom offerings, even their wave offering to the LORD.
Thus you also shall offer a wave offering to the LORD of all your tithes, which you receive of the children of Yisra'el; and of it you shall give the LORD's wave offering to Aharon the Kohen.
Therefore you shall tell them, When you heave the best of it from it, then it shall be reckoned to the Levites as the increase of the threshing floor, and as the increase of the winepress.
