Nehemiah 12:44-46

44On that day men were appointed over the storerooms, the contributions, the firstfruits, and the tithes, to gather into them the portions required by the Law for the priests and for the Levites according to the fields of the towns, for Judah rejoiced over the priests and the Levites who ministered.

45And they performed the service of their God and the service of purification, as did the singers and the gatekeepers, according to the command of David and his son Solomon.

46For long ago in the days of David and Asaph there were directors of the singers, and there were songs of praise and thanksgiving to God.
