Philip Schaff's Popular Commentary (4 vols)
Revelation 18 - Introduction
The chapter before us is occupied with the fall of Babylon, and it naturally divides itself into three parts. The first contains the announcement of the city's fall (Revelation 18:1-3); the second is a powerful description of amazement and lamentation over her fate, proceeding from all who had been dependent upon her (Revelation 18:4-20); the third points out the completeness and irremediableness of her ruin (Revelation 18:21-24).
