Nehemiah 12:46-47

Young's Literal Translation

⁴⁶ for in the days of David and Asaph of old [were] heads of the singers, and a song of praise and thanksgiving to God.

⁴⁷ And all Israel in the days of Zerubbabel, and in the days of Nehemiah, are giving the portions of the singers, and of the gatekeepers, the matter of a day in its day, and are sanctifying to the Levites, and the Levites are sanctifying to the sons of Aaron.
