1 Chronicles 25:5-7

Good News Translation

⁵ God gave to Heman, the king's prophet, these fourteen sons and also three daughters, as he had promised, in order to give power to Heman. ⁶ All of his sons played cymbals and harps under their father's direction, to accompany the Temple worship. And Asaph, Jeduthun, and Heman were under orders from the king.

⁷ All these twenty-four men were experts; and their fellow Levites were trained musicians. There were 288 men in all.
