Nehemiah 12:27-30

27Now at the dedication of the wall of Jerusalem they sought out the Levites from all their places, to bring them to Jerusalem so that they could celebrate the dedication with joy, with songs of thanksgiving and with songs 1to the accompaniment of cymbals, harps, and lyres. 28So the sons of the singers were assembled from the territory around Jerusalem, and from 2the villages of the Netophathites, 29from Beth-gilgal and from their fields in Geba and Azmaveth, because the singers had built themselves villages around Jerusalem. 30The priests and the Levites 3purified themselves; they also purified the people, the gates, and the wall.
