Then David assigned some of the Levites to the Chest of God to lead worship—to intercede, give thanks, and praise the God of Israel. Asaph was in charge; under him were Zechariah, Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-Edom, and Jeiel, who played the musical instruments. Asaph was on percussion. The priests Benaiah and Jahaziel blew the trumpets before the Chest of the Covenant of God at set times through the day.
