Ezra 3:8

8 Zerubbabel (who was Shealtiel's son), Jeshua (who was Jozadak's son), and the rest of the Jews, (the priests, Levites, and all the others who had come back from exile to Jerusalem) began to rebuild the temple. This happened in the second month of the second year following their return to [the site] of God's house in Jerusalem. They began by appointing the Levites who were at least 20 years old to direct the work on the LORD's house.
