Thus you shall also offer a heave offering to the Lord from all your tithes which you receive from the children of Israel, and you shall give the Lord’s heave offering from it to Aaron the priest.
Therefore you shall say to them: ‘When you have lifted up the best of it, then the rest shall be accounted to the Levites as the produce of the threshing floor and as the produce of the winepress.
It shall be from the children of Israel for Aaron and his sons by a statute forever. For it is a heave offering; it shall be a heave offering from the children of Israel from the sacrifices of their peace offerings, that is, their heave offering to the Lord.
