Nehemiah 12:27-30

When the wall of Jerusalem was offered as a gift to God, they asked the Levites to come from wherever they lived to Jerusalem to celebrate with joy the gift of the wall. They were to celebrate with songs of thanksgiving and with the music of cymbals, harps, and lyres. They also brought together singers from all around Jerusalem, from the Netophathite villages, from Beth Gilgal, and from the areas of Geba and Azmaveth. The singers had built villages for themselves around Jerusalem. The priests and Levites made themselves pure, and they also made the people, the gates, and the wall of Jerusalem pure.
