1 Chronicles 15:16-24

Then David spoke to the chiefs of the Levites to appoint their relatives the singers, with instruments of music, harps, lyres, loud-sounding cymbals, to raise sounds of joy. So the 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, and with them their relatives of the second rank, Zechariah, Ben, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-edom and Jeiel, the gatekeepers. So the singers, Heman, Asaph and Ethan were appointed to sound aloud cymbals of bronze; and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah and Benaiah, with harps tuned to alamoth; and Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel and Azaziah, to lead with lyres tuned to the sheminith. Chenaniah, chief of the Levites, was in charge of the singing; he gave instruction in singing because he was skillful. Berechiah and Elkanah were gatekeepers for the ark. Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah and Eliezer, the priests, blew the trumpets before the ark of God. Obed-edom and Jehiah also were gatekeepers for the ark.
