EZR 3:8

8 In the second month of the second year after arriving at God's Temple in Jerusalem, Zerubbabel, son of Shealtiel, Jeshua, son of Jozadak, and those with them—the priests, the Levites, and everyone who had come back to Jerusalem from captivity—began the work. They put Levites twenty years and older in charge of building the Lord's Temple.
