On that day men were appointed to be in charge of the storerooms for the gifts, the first part of the harvest, and the tithes. They were responsible to collect these from the fields as required by the law for the priests and Levites, for all the people of Judah valued the priests and Levites and their work.
They performed the service of their God and the service of purification, as required by the laws of David and his son Solomon, and so did the singers and the gatekeepers.
The custom of having choir directors to lead the choirs in hymns of praise and thanks to God began long ago in the days of David and Asaph.
So now, in the days of Zerubbabel and of Nehemiah, the people brought a daily supply of food for the singers, the gatekeepers, and the Levites. The Levites, in turn, gave a portion of what they received to the priests, the descendants of Aaron.
