Ezra 8:15-20

And I gathered them together to the river that runneth to Ahava; and there abode we in tents 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, men of understanding. And I sent them with commandment unto Iddo the chief at the place Casiphia, and I told them what they should say unto Iddo, and to his brethren the Nethinims, at the place Casiphia, that they should bring unto us ministers for the house of our God. And 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; 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; also of the Nethinims, whom David and the princes had appointed for the service of the Levites, two hundred and twenty Nethinims: all of them were expressed by name.
