16David told the leaders of the Levites to appoint their fellow Levites as musicians to make a joyful sound with musical instruments: lyres, harps and cymbals. 17So the Levites appointed Heman son of Joel; from his relatives, Asaph son of Berekiah; and from their relatives the Merarites, Ethan son of Kushaiah; 18and with them their relatives next in rank: Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-Edom and Jeiel, the gatekeepers. 19The musicians Heman, Asaph and Ethan were to sound the bronze cymbals; 20Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah and Benaiah were to play the lyres according to alamoth, 21and Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, Jeiel and Azaziah were to play the harps, directing according to sheminith. 22Kenaniah the head Levite was in charge of the singing; that was his responsibility because he was skillful at it.
