"Moreover David and the captains of the host set apart for the service certain of the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with harps, with psalteries, and with cymbals: and the number of them that did the work according to their service was: of the sons of Asaph: Zaccur, and Joseph, and Nethaniah, and Asharelah, the sons of Asaph, under the hand of Asaph, who prophesied after the order of the king.  Of Jeduthun; the sons of Jeduthun: Gedaliah, and Zeri, and Jeshaiah, Hashabiah, and Mattithiah, six, under the hands of their father Jeduthun with the harp, who prophesied in giving thanks and praising Jehovah.  Of Heman; the sons of Heman: Bukkiah, Mattaniah, Uzziel, Shebuel, and Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, and Romamti-ezer, Joshbekashah, Mallothi, Hothir, Mahazioth.  All these were the sons of Heman the king's seer in the words of God, to lift up the horn.  And God gave to Heman fourteen sons and three daughters.  All these were under the hands of their father for song in the house of Jehovah, with cymbals, psalteries, and harps, for the service of the house of God; Asaph, Jeduthun, and Heman being under the order of the king.  And the number of them, with their brethren that were instructed in singing unto Jehovah, even all that were skilful, was two hundred fourscore and eight.  And they cast lots for their offices, all alike, as well the small as the great, the teacher as the scholar."
