For versatility of expression and brilliance of imagery Isaiah had no superior, not even a rival. His style marks the climax of Hebrew literary art. Epigrams and metaphors, particularly of flood, storm, and sound (1:13; 5:8, 22; 8:8; 10:22; 28:17, 20; 30:28, 30), interrogation and dialogue (6:8; 10:8f.), antithesis and alliteration (1:18; 3:24; 17:10, 12), hyperbole and parable (2:7; 5:1-7; 28:23-29), even paronomasia, or play upon words (5:7; 7:9), characterize Isaiah’s book as the great masterpiece of Hebrew literature.
