1 Chronicles 25:1-8

David and the commanders of the army chose some of the sons of Asaph, Heman, and Jeduthun to preach and play harps, lyres, and cymbals. Here is a list of the men who served in this way: Asaph’s sons who served were Zaccur, Joseph, Nethaniah, and Asarelah. King David chose Asaph to preach, and Asaph directed his sons. Jeduthun’s sons who served were Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah. There were six of them, and Jeduthun directed them. He preached and used a harp to give thanks and praise to the LORD. Heman’s sons who served were Bukkiah, Mattaniah, Uzziel, Shubael, Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, Romamti-Ezer, Joshbekashah, Mallothi, Hothir, and Mahazioth. All these were sons of Heman, David’s seer. God promised to make Heman strong, so Heman had many sons. God gave him fourteen sons and three daughters. Heman directed all his sons in making music for the Temple of the LORD with cymbals, lyres, and harps; that was their way of serving in the Temple of God. King David was in charge of Asaph, Jeduthun, and Heman. These men and their relatives were trained and skilled in making music for the LORD. There were two hundred eighty-eight of them. Everyone threw lots to choose the time his family was to serve at the Temple. The young and the old, the teacher and the student, had to throw lots.
