And in that day His feet will stand on the Mount of Olives,
Which faces Jerusalem on the east.
And the Mount of Olives shall be split in two,
From east to west,
Making a very large valley;
Half of the mountain shall move toward the north
And half of it toward the south.
Then you shall flee through My mountain valley,
For the mountain valley shall reach to Azal.
Yes, you shall flee
As you fled from the earthquake
In the days of Uzziah king of Judah.
Thus the Lord my God will come,
And all the saints with You.
Zechariah 14:4-5

Why would the saints of God who are still alive at His coming have to flee? IMO I think this is speaking about the future event that came in 70AD.
I see Zechariah 14 as being prophetic of Jerusalem being destroyed in 70AD and also how Christ will return by the description mentioned in Matthew 24:27 and Acts 1:11 not literally planting His feet on the Mt. of Olives, from the air as He destroys the beast and false prophet and all the nations that followed after them.
The Mt. of Olives has much significance in the OT and NT. King David worshipped God on the summit and later how the Tenth Roman Legion camped on the Mt of Olives when they destroyed Jerusalem in 70AD. Jesus prayed there and taught from the Mt of Olives. It's a place of great Jewish history.
I see the prophetic of Jesus not actually stepping foot on the Mt of Olives, but that He returns with great power and authority as He fights the last battle of the evil stronghold the beast (Satan) has against Jerusalem. Rev 19:11-21
I just have to dig deeper into this one of these days.
