All these were under the hands of their father for song in the house of the LORD, with cymbals, psalteries, and harps, for the service of the house of God, according to the king's order to Asaph, Jeduthun, and Heman.
All these were under the hands of their father. Asaph had four sons, Jeduthun six, and Heman fourteen, equal to twenty-four -making the musicians, with their brethren the singers, an amount of 288; for, like the priests and Levites, they were divided into twenty-four courses of twelve men each, equal to 288, who served a week in rotation; and these, half of whom officiated every week with a proportionate number of assistants, verse skillful and experienced musicians, capable of leading and instructing the general musical corps, which comprised no less than 4,000 (1 Chronicles 23:5).
