1 Chronicles 25:1, 3

David and the army commanders then appointed men from the families of Asaph, Heman, and Jeduthun to proclaim God’s messages to the accompaniment of lyres, harps, and cymbals. Here is a list of their names and their work

From the sons of Jeduthun, there were Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six in all. They worked under the direction of their father, Jeduthun, who proclaimed God’s messages to the accompaniment of the lyre, offering thanks and praise to the LORD.
