1 Chronicles 15:17-21

So the Levites appointed Heman the son of Joel, and from his relatives, Asaph the son of Berechiah; and from the sons of Merari their relatives, Ethan the son of Kushaiah,

and with them their relatives of the second rank, Zechariah, Ben, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-edom, and Jeiel, the gatekeepers.

So the singers, Heman, Asaph, and Ethan, were appointed to sound aloud cymbals of bronze;

and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah, with harps tuned to alamoth;

and Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel, and Azaziah, to lead with lyres tuned to the sheminith.
