Ezra 3:8 And in the second year of their coming in unto the house of God, to Jerusalem, in the second month, began Zerubbabel son of Shealtiel, and Jeshua son of Jozadak, and the remnant of their brethren the priests and the Levites, and all those coming from the captivity to Jerusalem, and they appoint the Levites from a son of twenty years and upward, to overlook the work of the house of Jehovah. (Young's Literal Translation)
