Nehemiah 12:45-47

Young's Literal Translation

⁴⁵ And the singers and the gatekeepers keep the charge of their God, even the charge of the cleansing -- according to the command of David [and] Solomon his son,

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.
