1 Chronicles 25:1-6

ISV(i) 1 The MusiciansAlong with officers in his army, David consecrated to assist in service to the descendants of Asaph, Heman, and Jeduthun those who prophesy with lyres, harps, and cymbals.
The list of those who participated in this service included: 2 from the descendants of Asaph: Zaccur, Joseph, Nethaniah, and Asarelah, sons of Asaph mentored by Asaph himself, who prophesied under the supervision of the king; 3 from Jeduthun, these six of his descendants: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, mentored by their father Jeduthun, who played a lyre and prophesied, giving thanks and praise to the LORD; 4 from Heman, these descendants: Bukkiah, Mattaniah, Uzziel, Shebuel, Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, Romamti-ezer, Joshbekashah, Mallothi, Hothir, and Mahazioth. 5 All of these were descendants of Heman the king’s seer, according to God’s promise to exalt him, since God had given Heman fourteen sons and three daughters. 6 They were all under their father’s supervision regarding music in the Temple of the LORD with cymbals, harps, and lyres for the service of the Temple of God.
Asaph, Jeduthun, and Heman were under command of the king.
