“In view of all this, we are making a binding agreement, putting it in writing, and our leaders, our Levites and our priests are affixing their seals to it.” 

Nehemiah 9:38

“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. A 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. The people of Israel, including the Levites, are to bring their contributions of grain, new wine and olive oil to the storerooms, where the articles for the sanctuary and for the ministering priests, the gatekeepers and the musicians are also kept. “We will not neglect the house of our God. 

Nehemiah 10:28-39

But while all this was going on, I was not in Jerusalem, for in the thirty-second year of Artaxerxes king of Babylon I had returned to the king. Some time later I asked his permission and came back to Jerusalem. Here I learned about the evil thing Eliashib had done in providing Tobiah a room in the courts of the house of God. I was greatly displeased and threw all Tobiah’s household goods out of the room. I gave orders to purify the rooms, and then I put back into them the equipment of the house of God, with the grain offerings and the incense. 

Nehemiah 13:6-9
