Heman directed all his sons in making music for the Temple of the Lord with cymbals, lyres, and harps; that was their way of serving in the Temple of God. King David was in charge of Asaph, Jeduthun, and Heman.
Jeduthun’s sons who served were Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah. There were six of them, and Jeduthun directed them. He preached and used a harp to give thanks and praise to the Lord.
