strange as it may seem, the City of Jerusalem as it existed in the time of Christ Jesus was also reckoned to be the "City of Seven Hills." This fact was well recognized in Jewish circles. In the Pirke de-Rabbi Eliezer, an 8th century midrashic narrative (section 10), the writer mentioned without commentary (showing that the understanding was well known and required no defense) that "Jerusalem is situated on seven hills" (recorded in The Book of Legends, edited by Bialik and Ravnitzky, p. 371, paragraph 111). And, so it was. Those "seven hills" are easy to identify.
If one starts with the Mount of Olives just to the east of the main City of Jerusalem (but still reckoned to be located within the environs of Jerusalem), there are three summits to that Mount of Olives:
The northern summit (hill) is called Scopus [Hill One],
The middle summit (hill) was called Nob [Hill Two],
The highest point of Olivet itself, and the southern summit (hill) was called in the Holy Scriptures the "Mount of Corruption" or "Mount of Offence" [Hill Three] (II Kings 23:13).
On the middle ridge between the Kedron and the Tyropoeon Valleys there was (formerly) in the south "Mount Zion" [Hill Four] (the original "Mount Zion" and not the later southwest hill that was later called by that name),
The "Ophel Mount" [Hill Five],
To the north of that the "Rock" around which "Fort Antonia" was built [Hill Six],
And finally, there was the southwest hill itself [Hill Seven] that finally became known in the time of Simon the Hasmonean as the new "Mount Zion."
This makes "Seven Hills" in all.
