Actually, the Jews are already in Judea, and Jerusalem has been "restored" (Joel 3:1). That part precedes the nations being gathered against Jerusalem, to the valley of judgment, and Jerusalem being "captured". (Zechariah 14:1-3). "Israel" remains
"scattered among the nations" (Joel 3:2)
. The valley of judgment (Jehoshaphat), is call Har-Magedon in Revelation 16:16. Your source bible, written for the glorification of a gay king of England, seems to have led you down the broad way (Matthew 7:13). The gathering of the nations against Jerusalem, is in effect (Zech 14:1 & Joel 3:2 & Rev 16:13-16). It is Judah/Jews who will fight at Jerusalem (Zechariah 14:14) and the spoils "will be divided among you" (Zech 14:1).
Joel 3:
1“For behold, in those days and at that time,
When I restore the fortunes of Judah and Jerusalem,
2I will gather all the nations
And bring them down to the valley of Jehoshaphat.
Then I will enter into judgment with them there
On behalf of My people and My inheritance, Israel,
Whom they have scattered among the nations;
And they have divided up My land.
Zechariah 14:1-3
1Behold, a day is coming for the LORD when the spoil taken from you will be divided among you.
2For I will gather all the nations against Jerusalem to battle, and the city will be captured, the houses plundered, the women ravished and half of the city exiled, but the rest of the people will not be cut off from the city.
3Then the LORD will go forth and fight against those nations, as when He fights on a day of battle.
