Nehemiah 12:44-46

44On that day men were appointed over the storerooms for the contributions, first fruits, and tithes, to gather into them from the fields of the cities the portions prescribed by the law for the priests and the Levites, for the people of Judah took delight in the priests and Levites who were ministering.

45They performed the service of their God and the service of purification, along with the singers and gatekeepers, according to the commandment of David and his son Solomon.

46For long ago, in the days of David and Asaph, there had been directors for the singers and for the songs of praise and thanks to God.
