Ezra 3:7-8

They also gave money to the masons and the carpenters, and food, drink, and oil to the people of Sidon and Tyre to bring cedar logs from Lebanon to the sea, to Joppa, according to the permission which they had from Cyrus king of Persia. Now in the second month of the second year of their coming to the house of God at Jerusalem, Zerubbabel the son of Shealtiel, Jeshua the son of Jozadak, and the rest of their brethren the priests and the Levites, and all those who had come out of the captivity to Jerusalem, began work and appointed the Levites from twenty years old and above to oversee the work of the house of the LORD.
