Nehemiah 12:27-31

At the dedication of the wall of Jerusalem, they sent for the Levites wherever they lived and brought them to Jerusalem to celebrate the joyous dedication with thanksgiving and singing accompanied by cymbals, harps, and lyres. The singers gathered from the region around Jerusalem, from the settlements of the Netophathites, from Beth-gilgal, and from the fields of Geba and Azmaveth, for they had built settlements for themselves around Jerusalem. After the priests and Levites had purified themselves, they purified the people, the city gates, and the wall. Then I brought the leaders of Judah up on top of the wall, and I appointed two large processions that gave thanks. One went to the right on the wall, toward the Dung Gate.
