The Bible does 'Har-Meggidon' means 'a mountain of people gathered together' (Joel 3:2, Zechariah 12:3, Isaiah 29:7, Revelation 20:9, Isaiah 13:4, Ezekiel 32:18, Ezekiel 39:11, Zephaniah 2:1-2, Micah 4:11, etc).

These state all nations come against Jerusalem, and then the Source removes all the ungodly in one day...

Rabbinic Jews think they're Israel, and many of them are part of the problem with 'Jerusalem' being a 'Place of Peace' in the world - thus they also get removed in a day for denying the Bible.

If we analyse the timeline (Revelation 16:16-21, Zechariah 14:1-15, Joel 3:11-15, Isaiah 13:4-10): Armageddon is as the nations come against Jerusalem, and then the stars fall from the sky at the same time it takes place.

Since first writing this I've understood the Biblical prophetic timeline better:

Betelgeuse in the 'Orion constellation' going supernova (Isaiah 13:10, Ezekiel 32:7, Zechariah 14:7) as all Nations (including Judah - Zephaniah 1:4, Zechariah 12:2, Zechariah 14:14) gather around Jerusalem.

The Parable of the Fig before Summer (Matthew 24:29-35, Mark 13:24-31, Luke 21:25-33) is that as all Nations gather, then the sun & moon is darkened, and the stars/meteorites fall from the sky (Revelation 6:12-17).

The citation of the 'Fig before Summer' is in reference to Isaiah 28:4, where the Pharisaic authors (John, Saul, & Simon petros) turned the Messiah (Chief Corner Stone) into a Covenant of Death (Isaiah 28:15+18) - where in Hebrew Saul, and Sheol are spelled the same; meaning that Paul is fulfilling the role the devil.

For the fake Rabbinic Zionist who believe they're the ones to be saved, the Messiah is symbolically named 'Your Divine Being (Elohik) Zion' in Psalms 146:10, Psalms 147:12, Isaiah 52:7, and all of these verses Zion becomes the Creators dwelling place.

Thus to summarise the Messiah (King David), first came as Yeshua (Isaiah 52:10) to warn of the Exile Among the Nations for murdering him.

Then the Messiah returns with the name Zion/Zan before the Closure of the Bed of Adultery (Isaiah 28:9-19+20-21, Revelation 2:22), and Judgement Day as all Nations are about to start WW3 in the Middle East.
