Nehemiah 12:44-46

44And on that same day men were appointed over the rooms that housed the supplies, contributions, firstfruits, and tithes. The portions specified by the Law for the priests and Levites were gathered into these storerooms from the fields of the villages, because Judah rejoiced over the priests and Levites who were serving.

45They performed the service of their God and the service of purification, along with the singers and gatekeepers, as David and his son Solomon had prescribed. 46For long ago, in the days of David and Asaph, there were directors for the singers and for the songs of praise and thanksgiving to God.
