Zechariah 14:1-5 describes this return to earth more specifically.
Behold, the day of the Lord is coming,And your spoil will be divided in your midst.
For I will gather all the nations to battle against Jerusalem;The city shall be taken,The houses rifled,And the women ravished.Half of the city shall go into captivity,
But the remnant of the people shall not be cut off from the city.
Then the Lord will go forthAnd fight against those nations,As He fights in the day of battle.
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 all the saints with You
Masoretic VS Septuagint (thank you MEECHA):
Azal (אצל
, or Azel, is a location mentioned in the Book of Zechariah 14:5, in Bibles that use the Hebrew Masoretic Text as the source for this verse. In Bibles that follow the Greek Septuagint (LXX) rendering, depending upon the source manuscript used, Azal is transcribed Jasol (ιασολ, pronounced "Yasol"), Jasod (a corruption of Jasol), or Asael (ασαηλ
:
And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah.[1], King James Version
The valley between the hills will be filled in, yes, it will be blocked as far as Jasol, it will be filled in as it was by the earthquake in the days of Uzziah king of Judah[2], New Jerusalem Bible
...There is evidence that Clermont-Ganneau's theory and the LXX rendering of Zechariah 14:5 are correct. In 1984, Israeli geologists Daniel Wachs and Dov Levitte identified the location of a large landslide on the Mount of Olives that is directly adjacent to both Wady Yasul (Nahal Etzel) and the area of the ancient kings' gardens at the juncture of the Hinnom and Kidron Valleys.[8]. Wachs' and Levitte's discovery validates Jewish historian Flavius Josephus' account of an earthquake-caused landslide during King Uzziah's reign blocking up the kings' gardens in the valley.[9] It also accords with the LXX rendering of Zechariah 14:5, which states a valley will be blocked up as far as Azal. Additionally, the Israelis named this valley אצל (Etzel, or Etsel), with the same Hebrew spelling of Azal (אצל

Azal: A Longtime Mystery Rediscovered
This is a synopsis of the detailed study, The Truth Hidden Right in Front of Our Eyes.
Azal (אצל
, or Azel, is the location mentioned in Zechariah 14:5 in bibles that use the Hebrew Masoretic Text (MT) as the source for this verse.
And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah.
Zechariah 14:5, King James Version
In bibles that follow the Greek Septuagint (LXX) rendering, depending upon the source manuscript used, Azal is transcribed Jasol (ιασολ, pronounced Yasol), Jasod (a corruption of Jasol), or Asael (ασαηλ
:
The valley between the hills will be filled in, yes, it will be blocked as far as Jasol, it will be filled in as it was by the earthquake in the days of Uzziah king of Judah.
Zechariah 14:5, New Jerusalem Bible
These very different renderings from two authoritative sources obscure a clear understanding of Zechariah 14:5. Another obscurant factor is an almost universal ignorance, existent for many centuries until now, of what and where Azal is, or was. This is largely due to the fact that no known writing authored prior to the late 19th century clarifies this mystery.....
