1 Chronicles 15:16-19

16David told the Levite leaders to appoint some of their relatives to serve as musicians. They were expected to play music on harps, lyres, and cymbals to produce joyful music for singing.

17So the Levites appointed Heman, son of Joel, and from his relatives they appointed Asaph, Berechiah’s son. From their own relatives, Merari’s descendants, they appointed Ethan, son of Kushaiah.

18In addition, they appointed their relatives from the second division: Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, and Mikneiah. Obed Edom and Jeiel were appointed gatekeepers.

19The musicians Heman, Asaph, and Ethan were appointed to play bronze cymbals.
