1 Chronicles 25:5-8

5All these were the sons of Heman 1the king’s seer to 2exalt him according to the words of God, for God gave fourteen sons and three daughters to Heman. 6All of these were under the 3direction of their father to sing in the house of the Lord, 4with cymbals, harps, and lyres, for the service of the house of God. 5Asaph, Jeduthun, and Heman were 6under the direction of the king. 7Their number who were trained in singing to the Lord, with their relatives, all who were skillful, was 7288. 88They cast lots for their duties, all alike, the small as well as the great, the teacher as well as the pupil.
