20 Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah were to play harps according to Alamoth; 21 but Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel, and Azaziah were to lead with lyres according to the Sheminith. 22 Chenaniah, leader of the Levites in music, was to direct the music, for he understood it. 23 Berechiah and Elkanah were to be gatekeepers for the ark. 24 Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, were to blow the trumpets before the ark of God. Obed-edom and Jehiah also were to be gatekeepers for the ark.
