27Now at the dedication of the wall of Jerusalem they sought out the Levites in all their places, to bring them to Jerusalem to celebrate the dedication with rejoicing, with thanksgivings and with singing, with cymbals, harps, and lyres. 28The companies of the singers gathered together from the circuit around Jerusalem and from the villages of the Netophathites; 29also from Beth-gilgal and from the region of Geba and Azmaveth; for the singers had built for themselves villages around Jerusalem. 30And the priests and the Levites purified themselves; and they purified the people and the gates and the wall.
31aThen I brought the leaders of Judah up onto the wall, and appointed two great companies that gave thanks and went in procession.
42bAnd the singers sang with Jezrahiah as their leader. 43They offered great sacrifices that day and rejoiced, for God had made them rejoice with great joy; the women and children also rejoiced. The joy of Jerusalem was heard far away.
44On that day men were appointed over the chambers for the stores, the contributions, the first fruits, and the tithes, to gather into them the portions required by the law for the priests and for the Levites from the fields belonging to the towns; for Judah rejoiced over the priests and the Levites who ministered. 45They performed the service of their God and the service of purification, as did the singers and the gatekeepers, according to the command of David and his son Solomon. 46For in the days of David and Asaph long ago there was a leader of the singers, and there were songs of praise and thanksgiving to God. 47In the days of Zerubbabel and in the days of Nehemiah all Israel gave the daily portions for the singers and the gatekeepers. They set apart that which was for the Levites; and the Levites set apart that which was for the descendants of Aaron.
