David and the chiefs of the service also set apart for the service certain of the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with lyres, with harps, and with cymbals. The list of those who did the work and of their duties was:
Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shime-i, Hashabiah, and Mattithiah, six, under the direction of their father Jeduthun, who prophesied with the lyre in thanksgiving and praise to the Lord.
They were all under the direction of their father in the music in the house of the Lord with cymbals, harps, and lyres for the service of the house of God. Asaph, Jeduthun, and Heman were under the order of the king.
