Numbers 18:28-30

Modern English Version

²⁸ Thus you also will set apart an offering to the Lord from all the tithes which you receive from the children of Israel. Out of them you will give the offering of the Lord to Aaron the priest. ²⁹ Out of all your gifts you shall present every offering due to the Lord, from all the best of them, the consecrated part of them.

³⁰ You will say to them: When you have offered the best from it, then it will be counted to the Levites as the increase of the threshing floor, and as the increase of the winepress.
