These things shall be a perpetual ordinance for Aaron and his sons from the Israelites, for this is an offering, and it shall be an offering by the Israelites from their sacrifice of offerings of well-being, their offering to the Lord.
Thus you also shall set apart an offering to the Lord from all the tithes that you receive from the Israelites, and from them you shall give the Lord’s offering to the priest Aaron.
Say also to them: When you have set apart the best of it, then the rest shall be reckoned to the Levites as produce of the threshing floor and as produce of the winepress.
