The heads of the Levites were Hashabiah, Sherebiah, and Jeshua the son of Kadmiel, and their brothers opposite them, to praise and to give thanks, as commanded by David the man of God, [one] division [singing] in response to [the men in the opposite] division.

And at the dedication of the wall of Jerusalem they sought the Levites out of all their places, to bring them to Jerusalem, to keep the dedication with gladness, both with thanksgivings, and with singing, with cymbals, psalteries, and with harps.
