1 Chronicles 25:1-8

David and the chiefs of the service also set apart for the service the sons of Asaph, and of Heman, and of Jeduthun, who prophesied with lyres, with harps, and with cymbals. The list of those who did the work and of their duties was: Of the sons of Asaph: Zaccur, Joseph, Nethaniah, and Asharelah, sons of Asaph, under the direction of Asaph, who prophesied under the direction of the king. Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six, under the direction of their father Jeduthun, who prophesied with the lyre in thanksgiving and praise to the LORD. Of Heman, the sons of Heman: Bukkiah, Mattaniah, Uzziel, Shebuel and Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, and Romamti-ezer, Joshbekashah, Mallothi, Hothir, Mahazioth. All these were the sons of Heman the king’s seer, according to the promise of God to exalt him, for God had given Heman fourteen sons and three daughters. They were all under the direction of their father in the music in the house of the LORD with cymbals, harps, and lyres for the service of the house of God. Asaph, Jeduthun, and Heman were under the order of the king. The number of them along with their brothers, who were trained in singing to the LORD, all who were skillful, was 288. And they cast lots for their duties, small and great, teacher and pupil alike.
