Ezra 8:17-20

17And I gave them a commission to Iddo the chief, at the place Casiphia, and I put words in their mouths to say to Iddo [and] his brethren the Nethinim, at the place Casiphia, that they should bring to us ministers for the house of our 1God.

18And by the good hand of our 2God 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 his brethren, eighteen;

19and Hashabiah, and with him Isaiah of the sons of Merari, his brethren and their sons, twenty;

20and of the Nethinim, whom David and the princes had appointed for the service of the Levites, two hundred and twenty Nethinim: all of them were expressed by name.
