v1-6: The mighty angel announces the fall of Babylon the Great. This world-wide source and channel of evil is destroyed. The saints of God are commanded to "come out of her" (Jer 50.8; 51.6). To tolerate such things is to share in her sins.
v7: The description of Babylon is reminiscent of that of Tyre;
- she glorified herself, "I am a god" (Ezek 28.2,9);
- she lived luxuriously; beauty, ivory, blue, purple (Ezek 27.4-7; 28.4-5);
- "I sit as queen," "I am perfect in beauty … I sit in the seat of gods" (Ezek 27.3; 28.2).
v8: Her judgment will be sudden and decisive, "in one hour." The Lord shows His greater power, bringing her to destruction.
v9-10: The kings of the earth, having received wealth from Babylon, now mourn her fall.
v11-13: Similarly the merchants of the earth mourn. We see here the significant economic influence of Babylon, but also including the bodies and souls of men. Babylon's wealth came at a great cost to others.
v14-15: The merchants, seeking the things of this world, and believing Babylon's lies, stand terrified. Their fruit, in riches and splendour, disappears in one hour.
v16-19: The merchants are joined by the sea captains, and many who also earned their living by her trade. They speak only of the trade she generated, and the wealth they gained; they are ignorant of her evil influence. See also Ezek 27.29-32, where merchants and seamen mourned over the fall of Tyre. They too were ignorant of the spiritual realities, the evil influence.
The writer emphasises the suddenness of Babylon's fall, "in one hour." This is something expected by no one. All this schemes for riches come to nothing; many lose their hope.
v20: Compare 6.9-11; the fall of Babylon is God's vengeance upon her. It is no accident of history.
v21-24: A further description of Babylon's greatness and fall. Babylon was guilty of killing many prophets and saints. By her sorcery, she deceived the nations into worshipping her. The judgment against Babylon is severe, but certainly deserved.
Yet her defeat is followed by the reign of the beast, see 17.17.
