Moreover David and the captains of the host separated to the service of the sons of Asaph, and of Heman, and of Jedu´thun, who should prophesy with harps, with psalteries, and with cymbals: and the number of the workmen according to their service was:
Of Jedu´thun: the sons of Jedu´thun; Gedali´ah, and Zeri, and Jeshai´ah, Hashabi´ah, and Mattithi´ah, six, under the hands of their father Jedu´thun, who prophesied with a harp, to give thanks and to praise the Lord.
All these were under the hands of their father for song in the house of the Lord, with cymbals, psalteries, and harps, for the service of the house of God, according to the king's order to Asaph, Jedu´thun, and Heman.
And they gathered their brethren, and sanctified themselves, and came, according to the commandment of the king, by the words of the Lord, to cleanse the house of the Lord.
