Ezra 8:15-20

And I gathered them together to the river that runneth to Ahava; and there we encamped three days: and I viewed the people, and the priests, and found there none of the sons of Levi. Then 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. And 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. And 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; and Hashabiah, and with him Jeshaiah of the sons of Merari, his brethren and their sons, twenty; and 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.
