Ezra 3:8

And in the second year of their coming to the house of God in Jerusalem, in the second month, began Zorobabel the son of Salathiel, and Jesus the son of Josedec, and the rest of their brethren the priests and the Levites, and all who came from the captivity to Jerusalem, and they appointed the Levites, from twenty years old and upward, over the workmen in the house of the Lord.
