So the Levites appointed Heman the son of Joel, and from his relatives, Asaph the son of Berechiah; and from the sons of Merari their relatives, Ethan the son of Kushaiah,
Moreover, David and the commanders of the army set apart for the service some of the sons of Asaph and of Heman and of Jeduthun, who were to prophesy with lyres, harps and cymbals; and the number of those who performed their service was:
Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah and Mattithiah, six, under the direction of their father Jeduthun with the harp, who prophesied in giving thanks and praising the Lord.
All these were under the direction of their father to sing 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 direction of the king.
A Maskil of Ethan the Ezrahite. I will sing of the lovingkindness of the Lord forever; To all generations I will make known Your faithfulness with my mouth.
