From Jeduthun: Jeduthun’s sons:
Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah—six—under the authority of their father Jeduthun, prophesying to the accompaniment of lyres, giving thanks and praise to the Lord.

Heman and Jeduthun had with them trumpets and cymbals to play and musical instruments of God. Jeduthun’s sons were at the gate.

He assigned Obed-edom and his 68 relatives. Obed-edom son of Jeduthun and Hosah were to be gatekeepers.

With them were Heman, Jeduthun, and the rest who were chosen and designated by name to give thanks to the Lord—for His faithful love endures forever.

David and the officers of the army also set apart some of the sons of Asaph, Heman, and Jeduthun, who were to prophesy accompanied by lyres, harps, and cymbals. This is the list of the men who performed their service:

All these men were under their own fathers’ authority for the music in the Lord’s temple, with cymbals, harps, and lyres for the service of God’s temple. Asaph, Jeduthun, and Heman were under the king’s authority.

Obadiah the son of Shemaiah, son of Galal, son of Jeduthun; and Berechiah the son of Asa, son of Elkanah, who lived in the villages of Netophathite.

Asaph, Jeduthun, and Heman were under command of the king. They and their relatives who had been skillfully trained in singing to the LORD, numbered 288.
