We have here, I. An angel proclaiming the fall of Babylon (Rev 18:1, Rev 18:2). II. Assigning the reasons of her fall (Rev 18:3). III. Giving warning to all who belonged to God to come out of her (Rev 18:4, Rev 18:5), and to assist in her destruction (Rev 18:6-8). IV. The great lamentation made for her by those who had been large sharers in her sinful pleasures and profits (Rev 18:9-19). V. The great joy that there would be among others at the sight of her irrecoverable ruin (Rev 18:20, etc.).
