Ezra 8:16-20

16Then sent I for Eliezer, for Ariel, for Shemaiah, and for Elnathan, and for Jarib, and for Elnathan, and for Nathan, and for Zechariah, and for Meshullam, chief men; also for Joiarib, and for Elnathan, who were teachers. 17And I sent them forth unto Iddo the chief at the place Casiphia; and I told them what they should say unto Iddo, and his brethren the Nethinim, at the place Casiphia, that they should bring unto us ministers for the house of our God. 18And according to the good hand of our God upon us they brought us a man of discretion, of the sons of Mahli, the son of Levi, the son of Israel; and Sherebiah, with his sons and his brethren, eighteen; 19and Hashabiah, and with him Jeshaiah of the sons of Merari, his brethren and their sons, twenty; 20and of the Nethinim, whom David and the princes had given for the service of the Levites, two hundred and twenty Nethinim: all of them were mentioned by name.
