Nehemiah 12:45-47

12:45 They 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. 12:46 For 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. 12:47 So in the days of Zerubbabel and in the days of Nehemiah, all Israel was contributing the portions for the singers and gatekeepers, according to the daily need. They also set aside the portion for the Levites, and the Levites set aside the portion for the descendants of Aaron.
