Nehemiah 12:44-46

44On that same day men were placed in charge of the rooms that housed the supplies, contributions, firstfruits, and tenths. The legally required portions for the priests and Levites were gathered from the village fields, because Judah was grateful to 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 heads of the singers and songs of praise and thanksgiving to God.
