Ezra 3:8

8 So in the second month of the year after they came back to the site of the Temple in Jerusalem, they began work. Zerubbabel, Joshua, and the rest of their people, the priests, and the Levites, in fact all the exiles who had come back to Jerusalem, joined in the work. All the Levites twenty years of age or older were put in charge of the work of rebuilding the Temple.

Ezra 3:8 In-Context

6 Although the people had not yet started to rebuild the Temple, they began on the first day of the seventh month to burn sacrifices to the Lord.
7 The people gave money to pay the stonemasons and the carpenters and gave food, drink, and olive oil to be sent to the cities of Tyre and Sidon in exchange for cedar trees from Lebanon, which were to be brought by sea to Joppa. All this was done with the permission of Emperor Cyrus of Persia.
8 So in the second month of the year after they came back to the site of the Temple in Jerusalem, they began work. Zerubbabel, Joshua, and the rest of their people, the priests, and the Levites, in fact all the exiles who had come back to Jerusalem, joined in the work. All the Levites twenty years of age or older were put in charge of the work of rebuilding the Temple.
9 The Levite Jeshua and his sons and relatives, and Kadmiel and his sons (the clan of Hodaviah ) joined together in taking charge of the rebuilding of the Temple. (They were helped by the Levites of the clan of Henadad.)
10 When the builders started to lay the foundation of the Temple, the priests in their robes took their places with trumpets in their hands, and the Levites of the clan of Asaph stood there with cymbals. They praised the Lord according to the instructions handed down from the time of King David.
