Nehemiah 12:44-47

At that time the leaders appointed men to be in charge of the storerooms. These rooms were for the gifts, the first fruits, and the ten percent that the people brought. The Teachings said they should bring a share for the priests and Levites from the fields around the towns. The people of Judah were happy to do this for the priests and Levites who served. They performed the service of their God in making things pure. The singers and gatekeepers also did their jobs, as David had commanded his son Solomon. Earlier, in the time of David and Asaph, there was a leader of the singers and of the songs of praise and thanksgiving to God. So it was in the days of Zerubbabel and Nehemiah. All the people of Israel gave something to the singers and gatekeepers, and they also set aside part for the Levites. Then the Levites set aside part for the descendants of Aaron.
