In the second year after their coming to the house of God at Jerusalem, in the second month, Zerubbabel son of Shealtiel and Jeshua son of Jehozadak began [their work], and the remainder of their brothers the priests and the Levites and all who came from the captivity to Jerusalem. They appointed the Levites {from twenty years and older} to direct the work of the house of Yahweh.

Also Hashabiah and with him Jeshaiah, the sons of Merari, with his brothers and their sons, twenty [in total].

And from the temple servants, whom David and [his] officials had set up to serve the Levites, two hundred and twenty [in total]. All of them were registered by name.

twenty gold bowls worth one thousand darics, and two vessels of good polished bronze as precious as gold.
