Nehemiah 10:37-38

37“Moreover, we will bring to the storerooms of the house of our God, to the priests, the first of our ground meal, of our grain offerings, of the fruit of all our trees and of our new wine and olive oil. And we will bring a tithe of our crops to the Levites, for it is the Levites who collect the tithes in all the towns where we work.

38A priest descended from Aaron is to accompany the Levites when they receive the tithes, and the Levites are to bring a tenth of the tithes up to the house of our God, to the storerooms of the treasury.
