15:19So the singers, Heman, Asaph, and Ethan, were appointed to sound with cymbals of brass;

16:5Asaph the chief, and next to him Zechariah, Jeiel, and Shemiramoth, and Jehiel, and Mattithiah, and Eliab, and Benaiah, and Obededom: and Jeiel with psalteries and with harps; but Asaph made a sound with cymbals;

16:7Then on that day David delivered first this psalm to thank the LORD into the hand of Asaph and his brethren.
