Isaiah receives a prophecy against Babylon that he sees in a vision. The prophecy is introduced with the term "burden" which various scholars interpret as meaning an oracle, message, or heavy pronouncement from God. Babylon represents the spirit of worldly forces that resist God. Isaiah clearly sees this future prophecy, not with physical eyes but with spiritual insight, and it is credited fully to him though the destruction of Babylon he foresees does not occur for over 200 years.
