Moreover David and the captains of the army separated for the service [some] of the sons of Asaph, of Heman, and of Jeduthun, who [should] prophesy with harps, stringed instruments, and cymbals. And the number of the skilled men performing their service was:
Of the sons of Asaph: Zaccur, Joseph, Nethaniah, and Asharelah; the sons of Asaph [were] under the direction of Asaph, who prophesied according to the order of the king.
Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six, under the direction of their father Jeduthun, who prophesied with a harp to give thanks and to praise the LORD.
All these [were] under the direction of their father for the music [in] the house of the LORD, with cymbals, stringed instruments, and harps, for the service of the house of God. Asaph, Jeduthun, and Heman [were] under the authority of the king.
