⁴ As for Heman, from his sons:

Bukkiah, Mattaniah, Uzziel, Shubael and Jerimoth; Hananiah, Hanani, Eliathah, Giddalti and Romamti-Ezer; Joshbekashah, Mallothi, Hothir and Mahazioth. ⁵ (All these were sons of Heman the king’s seer. They were given to him through the promises of God to exalt him. God gave Heman fourteen sons and three daughters.)

⁶ All these men were under the supervision of their father for the music of the temple of the Lord, with cymbals, lyres and harps, for the ministry at the house of God.

Asaph, Jeduthun and Heman were under the supervision of the king.
