Ezra 8:15-23

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. Then I proclaimed a fast there at the river of Ahava, that we might humble ourselves before our God, to seek from Him the right way for us and our little ones and all our possessions. For I was ashamed to request of the king an escort of soldiers and horsemen to help us against the enemy on the road, because we had spoken to the king, saying, “The hand of our God is upon all those for good who seek Him, but His power and His wrath are against all those who forsake Him.” So we fasted and entreated our God for this, and He answered our prayer.
