David and the leaders of the army separated the sons of Asaph, Heman, and Jeduthun for special service. Their special service was to prophesy God's message with harps, lyres, and cymbals. Here is a list of the men who served this way:
From Jeduthun's family: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah. There were six of them. Jeduthun led his sons. Jeduthun used harps to prophesy and give thanks and praise to the Lord.
Heman's sons who served were Bukkiah, Mattaniah, Uzziel, Shubael, and Jerimoth; Hananiah, Hanani, Eliathah, Giddalti, and Romamti Ezer; Joshbekashah, Mallothi, Hothir, and Mahazioth.
All these men were Heman's sons. Heman was David's seer. God promised to make Heman strong. So Heman had many sons. God gave Heman fourteen sons and three daughters.
Heman led all his sons in singing in the Lord's temple. His sons used cymbals, lyres, and harps. That was their way of serving in God's temple. King David chose these men.
They threw lots to choose the different kinds of work each person was to do. Everyone was treated the same. Young and old were treated the same. And the teacher was treated the same as the student.
