Numbers 18:28-30

Evangelical Heritage Version

²⁸ In this way you also are to lift up an elevated offering for the Lord from every one of the tithes which you receive from the Israelites. From the tithes, you will give the elevated offering for the Lord to Aaron the priest. ²⁹ You will lift up every elevated offering for the Lord from the things given to you, from all the best, the holiest part of it.

³⁰ Tell the Levites this:

When you lift up the best part of the offering, it will be credited to the Levites as if it were produce from the threshing floor and the winepress.
