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 might celebrate the dedication with gladness, with hymns of thanksgiving and with songs 1to the accompaniment of cymbals, harps and lyres. 28So the sons of the singers were assembled from the district around Jerusalem, and from 2the villages of the Netophathites, 29from Beth-gilgal and from their fields in Geba and Azmaveth, for 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.
