Babylon the Great was remembered before God, to give her the cup of the wine of His fierce wrath...
Revelation 17 began with an interlude; a pause from the events of the great tribulation period. One of the seven angels with one of the seven bowls took John into the wilderness, a barren and desolate desert to show John why Babylon was singled out for judgement. Here John sees a woman dressed in scarlet and purple, adorned with the riches of the world; sitting upon a scarlet beast kingdom with seven heads and ten horns. The beast is full of blasphemy - blasphemous men and women who mock the God of heaven, while worshiping a false and malicious god. From this location, the woman demonstrates her ruling power over the kings of the earth, and the many waters - peoples, multitudes, nations and tongues.
The golden cup in her hands is full of vile things. The name written on her forehead was a mystery; Mystery, Babylon the Great, the Mother of Harlots and Abominations of the Earth; suggesting a middle east location. John also witnessed a plot of vengeance, a conspiracy, against the woman, organized by ten kings who control the affairs of the beast kingdom. The angel identifies the woman named Babylon the Great, as that great city, who rules over the kings of the earth. (how much more obvious can it be?)
After John is shown all these things, a second angel comes down from heaven having great power and, lightens the earth with his glory:18:1. John isn't taken in the spirit, when the second angel arrives, indicating that John and the first angel, are still in the wilderness, where the beast, and the woman are located: 17:3.
