Nehemiah 12:44-47

On that day men were appointed over the chambers for the stores, the contributions, the first fruits, and the tithes, to gather into them from the fields of the cities the portions required by the law for the priests and the Levites; for Judah rejoiced over the priests and Levites who served. And they performed the worship of their God and the service of purification; so did the singers and gatekeepers, as David and his son Solomon had commanded. For in the days of David and Asaph, in ancient times, there were leaders of singers, songs of praise and hymns of thanksgiving to God. So in the days of Zerubbabel and [later of] Nehemiah, all Israel would give the daily portions for the singers and the gatekeepers; and they set apart the consecrated portion for the Levites, and the Levites set apart the consecrated portion for the sons of Aaron [the priests].
