Ezra 8:17-20

17And I sent them to Iddo, the leading man at the place Casiphia, telling them what to say to Iddo and his brothers, the temple servants at the place Casiphia, that is, to bring us servants (ministers) for the house of our God.

18And as the good hand of our God was upon us, they brought us a man of understanding (insight) from the sons of Mahli, the son of Levi, the son of Israel, named Sherebiah, with his sons and his brothers (relatives), 18 men;

19and Hashabiah, and with him Jeshaiah of the sons of Merari, with his brothers (relatives) and their sons, 20 men;

20also 220 of the temple servants, whom David and the leaders had set apart [with their descendants] for the service of the Levites. They were all designated by name.
