Bible verse
Ezra 3:8
By the second month of the second year after they got to God’s house in Jerusalem, Zerubbabel (son of Shealtiel), Jeshua (son of Jozadak), and their fams, the priests, Levites, and all who came back from the exile, stepped up. They put the Levites twenty years old and up in charge of the work on the house of the LORD.
