Ezra 8:15-20

Now I gathered them by the river that flows to Ahava, and we camped there three days. And I looked among the people and the priests, and found none of the sons of Levi there. Then I sent for Eliezer, Ariel, Shemaiah, Elnathan, Jarib, Elnathan, Nathan, Zechariah, and Meshullam, leaders; also for Joiarib and Elnathan, men of understanding. And I gave them a command for Iddo the chief man at the place Casiphia, and I told them what they should say to Iddo and his brethren the Nethinim at the place Casiphia—that they should bring us servants for the house of our God. Then, by the good hand of our God upon us, they brought us a man of understanding, of the sons of Mahli the son of Levi, the son of Israel, namely Sherebiah, with his sons and brothers, eighteen men; and Hashabiah, and with him Jeshaiah of the sons of Merari, his brothers and their sons, twenty men; also of the Nethinim, whom David and the leaders had appointed for the service of the Levites, two hundred and twenty Nethinim. All of them were designated by name.
