1:1 Isaiah. Isaiah means “Jehovah is salvation” and is considered the greatest of Old Testament prophets. His book contains the most significant and greatest number of Messianic prophecies. It falls naturally into two divisions, chapters 1–39 and chapters 40–66. Liberals have long argued that the two divisions were written by two different authors. The only real evidence for this idea is the fact that certain explicit prophecies in the second division (e.g., Isaiah 45:1-4), were fulfilled long after the “first” Isaiah died, and liberals do not believe in predictive prophecy. The New Testament, however, including Christ Himself, quotes from both divisions, attributing all such quotes to Isaiah the prophet. Note, for example, Matthew 3:3; 12:17,18; Luke 3:4; John 12:38-41; Acts 8:28-34; Romans 10:16,20; and others. Jesus says that Isaiah wrote the prophecy in both Isaiah 6:9,10 (quoted in Matthew 13:14,15) and Isaiah 53:4 (quoted in Matthew 8:17), as well as other quotes from both divisions.
