15 And the children of the Levites bare the ark of God upon their shoulders with the staves thereon, as Moses commanded according to the word of the Lord.
16 And David spake to the chief of the Levites to appoint their brethren the singers, with instruments of music, psalteries and harps and cymbals, sounding aloud and lifting up the voice with joy.
17 So the Levites appointed Heman the son of Joel; and of his brethren, Asaph the son of Berechiah; and of the sons of Merari their brethren, Ethan the son of Kushaiah;
18 and with them their brethren of the second degree, Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Eliphelehu, and Mikneiah, and Obed-edom, and Jeiel, the doorkeepers.
19 So the singers, Heman, Asaph, and Ethan, were appointed, with cymbals of brass to sound aloud;
20 and Zechariah, and Aziel, and Shemiramoth, and Jehiel, and Unni, and Eliab, and Maaseiah, and Benaiah, with psalteries set to Alamoth;
21 and Mattithiah, and Eliphelehu, and Mikneiah, and Obed-edom, and Jeiel, and Azaziah, with harps set to the Sheminith, to lead.
