The men chosen to play the cymbals were Heman the son of Joel, his relative Asaph the son of Berechiah, and Ethan the son of Kushaiah from the Merari clan. Some of their assistants played the smaller harps: they were Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah. Others played the larger harps: they were Mattithiah, Eliphelehu, Mikneiah, Azaziah, and two of the temple guards, Obed-Edom and Jeiel.
