KJV(i)
28 And the sons of the singers gathered themselves together, both out of the plain country round about Jerusalem, and from the villages of Netophathi;
29 Also from the house of Gilgal, and out of the fields of Geba and Azmaveth: for the singers had builded them villages round about Jerusalem.
30 And the priests and the Levites purified themselves, and purified the people, and the gates, and the wall.
