History reveals the great city of Babylon was conquered in one night, without resistance, in 539 BC by Cyrus the Great. Revelation 14:8 reads:
14:8 And there followed another Angel, saying, Babylon is fallen, is fallen, that great citie, because she made all nations drink of the wine of the wrath of her fornication.
Not according to Jesus. It's the ONLY place that killed the prophets. That is a past event used for the marker. Only Jerusalem applies. God takes his anger out on Jerusalem in Rev. Read it closer.
The ones Jesus said Jerusalem killed. Scripture interprets scripture.
