Heman and Jeduthun were in charge of the music, including the trumpets, cymbals, and the other musical instruments used in praising God. The sons of Jeduthun guarded the entrance.
Joining them were Heman, Jeduthun, and the rest of those chosen and designated by name to give thanks to the Lord. (For his loyal love endures!)
David and the army officers selected some of the sons of Asaph, Heman, and Jeduthun to prophesy as they played stringed instruments and cymbals.
All of these were under the supervision of their fathers; they were musicians in the Lord’s temple, playing cymbals and stringed instruments as they served in God’s temple. Asaph, Jeduthun, and Heman were under the supervision of the king.
