Merari’s family were the helpers of Heman and Asaph, and they stood by Heman’s left side. In this group was Ethan son of Kishi. Kishi was Abdi’s son. Abdi was Malluch’s son.
So the Levites appointed Heman and his relatives Asaph and Ethan. Heman was Joel’s son. Asaph was Berekiah’s son. And Ethan, from the Merari family group, was Kushaiah’s son.
David and the commanders of the army chose some of the sons of Asaph, Heman, and Jeduthun to preach and play harps, lyres, and cymbals. Here is a list of the men who served in this way:
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.
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.
