1 Chronicles 15:19-23

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.

Chenaniah, chief of the Levites, was in charge of the singing; he gave instruction in singing because he was skillful.

Berechiah and Elkanah were gatekeepers for the ark.
