Nehemiah 12:24, 27, 43-46

These were the family leaders of the Levites: Hashabiah, Sherebiah, Jeshua, Binnui, Kadmiel, and other associates, who stood opposite them during the ceremonies of praise and thanksgiving, one section responding to the other, as commanded by David, the man of God.

For the dedication of the new wall of Jerusalem, the Levites throughout the land were asked to come to Jerusalem to assist in the ceremonies. They were to take part in the joyous occasion with their songs of thanksgiving and with the music of cymbals, harps, and lyres.

Many sacrifices were offered on that joyous day, for God had given the people cause for great joy. The women and children also participated in the celebration, and the joy of the people of Jerusalem could be heard far away. On that day men were appointed to be in charge of the storerooms for the offerings, the first part of the harvest, and the tithes. They were responsible to collect from the fields outside the towns the portions required by the Law for the priests and Levites. For all the people of Judah took joy in the priests and Levites and their work. They performed the service of their God and the service of purification, as commanded by 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 thanksgiving to God began long ago in the days of David and Asaph.
