Notice that this "whore", spiritual Babylon, sits on MANY WATERS...it is worldwide....
Come hither; I will shew unto thee the judgment of the great whore that sitteth upon many waters: ......And he saith unto me, The waters which thou sawest, where the whore sitteth, are peoples, and multitudes, and nations, and tongues. Revelation 17:1,15
This would be the counterfeit to God's people, who take the message of the Everlasting Gospel worldwide too....
And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Revelation 14:6
