here is what it says, for your edification
1.The word of the Lord, that came to Osee the son of Beeri, in the days of Ozias, Joathan, Achaz, and Ezechias kings of Juda, and in the days of Jeroboam the son of Joas king of Israel.And also read Isaiah 1:21 21 How is the faithful city, that was full of judgment, become a harlot? justice dwelt in it, but now murderers.
2 The beginning of the Lord's speaking by Osse: and the Lord said to Osee: Go, take thee a wife of fornications, and have of her children of fornications: for the land by fornication shall depart from the Lord.
Revelation 17:1 is clearly just as the rest of the book of the Apocalypse talking of the city of Jerusalem.
Firstly note that the harlot is separate from the beast -- so it can't be that Rome was both the harlot and the beast. This is also evident in the words off the High priests at Christ's trial John 19:15 "We have no king but Caesar"
This is also very very clear about Rev 17:1 which references Jeremiah 51:13 which says that Babylon sits by many waters. This is how John is linking Jerusalem as the new Babylon.
The Holy city has blasphemed and become like a harlot, a harlot arrayed in purple and scarlet - this echos Jeremiah 4:30 But when thou art spoiled what wilt thou do? though thou deckest thee with ornaments of gold, and paintest thy eyes with stibic stone, thou shalt dress thyself out in vain: thy lovers have despised thee, they will seek thy life.
Revelations 17:16 then says "And the beast will hate the harlot; they will make her desolate nad naked, and devour her flesh and burn her up with fire"
This is clearly a separation of the beast and the harlot and how the harlot-city of Jerusalem will be burnt up and devoured by the beast - the Empire.
This is so, so clear about the Roman Empire burning down Jerusalem as at the 10th "King" Vespasian did,p>Remember that Jerusalem had dominion i.e. spiritual dominionThe fall of the harlot-city happened in 69 AD in the same generation that had killed the Christ - Christ crucified in 30 AD and within 40 years (one generation) Jerusalem destroyed.
