1 Chronicles 25:3

of Jeduthun: The sons of Jeduthun: Gedaliah, and Zeri (or Izri), and Jeshaiah, Hashabiah, and Mattithiah, six, that is, including Shimei mentioned v. 17, under the hands of their father Jeduthun, working under his direction, who prophesied with a harp to give thanks and to praise the Lord. As it has been the practice of the prophets to rouse their prophetic spirit by the inspiring influence of music. so this became a custom in later times for the arousing of religious enthusiasm. Cf 2 Kings 3:15.
