16 David also commanded the chiefs of the Levites to appoint their brethren as the singers who should play loudly on musical instruments, on harps and lyres and cymbals, to raise sounds of joy. 17 So the Levites appointed Heman the son of Jo'el; and of his brethren Asaph the son of Berechi'ah; and of the sons of Merar'i, their brethren, Ethan the son of Kusha'iah; 18 and with them their brethren of the second order, Zechari'ah, Ja-a'ziel, Shemi'ramoth, Jehi'el, Unni, Eli'ab, Benai'ah, Ma-asei'ah, Mattithi'ah, Eliph'elehu, and Miknei'ah, and the gatekeepers O'bed-e'dom and Je-i'el. 19 The singers, Heman, Asaph, and Ethan, were to sound bronze cymbals; 20 Zechari'ah, A'zi-el, Shemi'ramoth, Jehi'el, Unni, Eli'ab, Ma-asei'ah, and Benai'ah were to play harps according to Al'amoth; 21 but Mattithi'ah, Eliph'elehu, Miknei'ah, O'bed-e'dom, Je-i'el, and Azazi'ah were to lead with lyres according to the Shem'inith. 22 Chenani'ah, leader of the Levites in music, should direct the music, for he understood it.
