Ezra 3:8

Now in the second year of their coming into the house of God in Jerusalem, in the second month, the work was taken in hand by Zerubbabel, the son of Shealtiel, and Jeshua, the son of Jozadak, and the rest of their brothers the priests and the Levites, and all those who had come from the land where they were prisoners to Jerusalem: and they made the Levites, of twenty years old and over, responsible for overseeing the work of the house of the Lord.⋮
