David and the officers of the army also set apart for the service the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with lyres, harps, and cymbals. The list of those who did the work and of their duties was:
Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, 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 for 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.
They gathered their brothers, sanctified themselves, and went in as the king had commanded, by the words of the Lord, to cleanse the house of the Lord.
