do cures to day and to morrow, and the third day I shall be perfected.
Luk 13:33 Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem.
Luk 13:34 O Jerusalem, Jerusalem, which killest the prophets, and stonest them that are sent unto thee; how often would I have gathered thy children together, as a hen doth gather her brood under her wings, and ye would not!
Luk 13:35 Behold, your house is left unto you desolate: and verily I say unto you, Ye shall not see me, until the time come when ye shall say, Blessed is he that cometh in the name of the Lord.

The great harlot is the "great city". The "great city" is Jerusalem.

Rev 17:18 And the woman which thou sawest is that great city, which reigneth over the kings of the earth.

Revelation, earlier, tells us which city is THE GREAT CITY: it is Jerusalem.

Rev 11:8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.

The Lord was crucified in Jerusalem, the great city, which is the great harlot.

Babylon, as a name for Jerusalem, is not unlike the comparison to other cities, such as as Sodom, Egypt, and Gomorrah; "spiritually is called Sodom and Egypt" Rev 11:8. (Isaiah 1:10; Jer. 23:14, Ezek. 16:44-56 all compare Jerusalem to Sodom. (also, Jesus in various NT scriptures, compared various Isralite cities to Sodom and Gomorrah by comparing judgment), Luke 10:12, Mark 6:11, Matthew 11:23-24, Matthew 10:15.)

As the woman sits on seven mountains, Jerusalem is built on seven mountains:

Rev 17:9 And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth.

Mt. Goath, Mt. Gareb, Mt. Acra, Mt. Bezetha, Mt. Zion, Mt. Ophel, and Mt. Moriah.

A second source, http://www.angelfire.com/pr/truth/whore.html, lists the same: Mount Zion, Mount Ophel, Mount Moriah, Mount Bezetha, Mount Acra, Mount Gareb, and Mount Goath.

A third confirming source, http://jesus-messiah.com/prophecy/rev-13.html, lists the same seven, and explains a bit more of why some authors list different mountains, and includes a map: "The seven hills identify Jerusalem not Rome: Jerusalem was a large city spreading outside the walls and covering the seven hills there during the time of Jesus and the Apostles: 1.) Mount Gared; 2.) Mount Goath; 3.) Mount Acra; 4.) Mount Bezetha; 5.) Mount Moriah; 6.) Mount Ophel; 7.) Mount Zion. For what ever reason, and by what ever hands and manipulation, Mt. Gared, Mt. Goath, Mt Acra, and Mt. Bezetha have been deleted from nearly all maps of Jerusalem."

http://www.unlimitedglory.org/txtrevcha4.htm "look at any old map showing the topography of Jerusalem immediately prior to 70 AD. In so doing I believe that you will find that the 7 hills of Moriah, Ophel, Zion, Bezetha, Golgotha,
