Ezra 8:15-20

Now I assembled them at the river that runs to Ahava, where we camped for three days; and when I observed the people and the priests, I did not find any Levites there. So I sent for Eliezer, Ariel, Shemaiah, Elnathan, Jarib, Elnathan, Nathan, Zechariah and Meshullam, leading men, and for Joiarib and Elnathan, teachers. I sent them to Iddo the leading man at the place Casiphia; and I told them what to say to Iddo and his brothers, the temple servants at the place Casiphia, that is, to bring ministers to us for the house of our God. According to the good hand of our God upon us they brought us a man of insight of the sons of Mahli, the son of Levi, the son of Israel, namely Sherebiah, and his sons and brothers, 18 men; and Hashabiah and Jeshaiah of the sons of Merari, with his brothers and their sons, 20 men; and 220 of the temple servants, whom David and the princes had given for the service of the Levites, all of them designated by name.
