Revelation 18:9

World government leaders will mourn when they see the collapse of the system that has sustained them and enabled them to live luxuriously. Committing fornication with her is a way of expressing sharing in Babylon’s luxury (cf. Ezekiel 26:16; Ezekiel 27:30-35). [Note: Johnson, p. 567.] Evidently fire will be the main cause of the city’s destruction (cf. Revelation 18:8; Revelation 18:18; Revelation 14:11; Revelation 17:16; Revelation 19:3). The smoke of her burning, the evidence of her fall, is what caused these rulers misery (cf. Genesis 19:28; Isaiah 34:10; Ezekiel 28:18).
