Nehemiah 12:27-31

27At the dedication of the wall of Jerusalem, they sought out the Levites from all the places they lived to bring them to Jerusalem to celebrate the dedication joyfully with songs of thanksgiving and songs accompanied by cymbals, harps, and lyres.

28The singers were also assembled from the district around Jerusalem and from the settlements of the Netophathites

29and from Beth Gilgal and from the fields of Geba and Azmaveth, for the singers had built settlements for themselves around Jerusalem.

30When the priests and Levites had purified themselves, they purified the people, the gates, and the wall.

31I brought the leaders of Judah up on top of the wall, and I appointed two large choirs to give thanks. One was to proceed on the top of the wall southward toward the Dung Gate.
