Asaph in Fausset's Bible Dictionary

("assembler".) 1. A Levite, son of Berachiah; one of David's choir leaders (1 Chronicles 6:39). An inspired seer, as well as a composer of music (2 Chronicles 29:30; Nehemiah 12:46). "The sons of Asaph" were poets and musical composers of the school founded by him; as Heman and Jeduthun also were heads of schools of sacred inspired music. 1 Chronicles 25:1; 2 Chronicles 20:14; Ezra 2:41; Psalm 50; 73; 83, are all attributed to his authorship; but 83, celebrates the victory of Jehoshaphat long after Asaph's time, therefore "Asaph" in this psalm's title must mean "one of the school of Asaph." 2. 2 Kings 18:18; 2 Kings 18:37. 3. Nehemiah 2:8. 4. Nehemiah 11:17.
