16Then David spoke to the chiefs of the Levites 1to appoint their relatives as the singers, with musical instruments, harps, lyres, and cymbals, playing to raise sounds of joy. 17So 2the Levites appointed Heman the son of Joel, and from his relatives, Asaph the son of Berechiah; and from the sons of Merari their relatives, Ethan the son of Kushaiah, 18and with them their relatives of the second rank, Zechariah, 3Ben, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-edom, and Jeiel, the gatekeepers. 19So the singers, Heman, Asaph, and Ethan, were appointed to sound aloud cymbals of bronze; 20and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah, with harps tuned to 45alamoth; 21and Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel, and Azaziah, to lead with 6lyres tuned to 7the sheminith. 22Chenaniah, chief of the Levites, was in charge of the singing; he gave instruction in singing because he was skillful. 23Berechiah and Elkanah were gatekeepers for the ark. 24Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, 8blew the trumpets before the ark of God.
