1 Chronicles 25:3-7

Of Jeduthun, the sons of Jeduthun: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six in all, under the direction of their father Jeduthun with the harp, who prophesied in giving thanks and praising the Lord.

Of Heman, the sons of Heman: Bukkiah, Mattaniah, Uzziel, Shebuel and Jerimoth, Hananiah, Hanani, Eliathah, Giddalti and Romamti-ezer, Joshbekashah, Mallothi, Hothir, and Mahazioth.

All these were the sons of Heman the king’s seer to exalt him according to the words of God, for God gave fourteen sons and three daughters to Heman.

All of these were under the direction of their father to sing 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 direction of the king.

Their number who were trained in singing to the Lord, with their relatives, all who were skillful, was 288. Divisions of the Musicians
