Nehemiah 12:46-47

46For long ago, in the days of David and Asaph, there had been directors for the musicians and for the songs of praise and thanksgiving to God. 47So in the days of Zerubbabel and of Nehemiah, all Israel contributed the daily portions for the musicians and the gatekeepers. They also set aside the portion for the other Levites, and the Levites set aside the portion for the descendants of Aaron.
