Zion is the location. It is not the people who call themselves Zionist. Zion is south of the so called Temple Mount. The second Temple was located just south of the Temple Mount. This Mount is about the size of a Roman Camp. It looked down upon the Temple.
2. A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread upon the mountains: a great people and a strong; there has not been ever the like, neither shall be any more after it, even to the years of many generations.
This is a prophetic screenshot of the coming war. The only other war comparable is not in history, it's in the future. That will be just before the universe is destroyed.
3. A fire devours before them; and behind them a flame burns: the land is as the garden of Eden before them, and behind them a desolate wilderness; yea, and nothing shall escape them.
This explains a coming war tactic. Rich fertil farmland will be nuked. They will do this to starve out those who would be still alive. The USA did something like this to the Native Americans by killing off the North American Buffalo.
4-5. The appearance of them is as the appearance of horses; and as horsemen, so shall they run. Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devours the stubble, as a strong people set in battle array.
Chariots with the noise of fire leaping on the top of the mountains? This would be fighter jets. These jets have been ordered to destroy everything.
6. Before their face the people shall be much pained: all faces shall gather blackness.
This verse introduces the paranormal warfare. I believe this will be demonic in nature.
7-8. They shall run like mighty men; they shall climb the wall like men of war; and they shall march everyone on his ways, and they shall not break their ranks: Neither shall one thrust another; they shall walk every one in his path: and when they fall upon the sword, they shall not be wounded.
Mighty men is a reference to human hybrids. Like in the days of Noah, fallen angels fathered children with human women. Falling on a sword and not hurt is in reference to them living beyond the 3 dimensions and time. It is said today that these creatures are in National Parks. Bullets having no effect on them.
9. They shall run to and fro in the city; they shall run upon the wall, they shall climb up upon the houses; they shall enter in at the windows like a thief.
There's no stopping this demonic hybrid army. Sounds like some antigravity thing going on here.
10. The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
These events is like a timestamp. We can compare this to the Book of Revelation. This is towards the end of the Great Tribulation. Not only does this demonic hybrid army is paranormal, they will be able to control earthquakes, using them as a weapon of war. When the sun, moon and stars are not shining, I believe this will be done by demonic technology. To simplify it, light can cancel out light by being out of phase. It's like two wave patterns out of phase creation darkness.
11. And Yahuah shall utter His voice before His army: for His camp is very great: for He is strong that executes His word: for the Day of Yahuah is great and very terrible; and who can abide it?
This is when Yahusha returns. Antichrist and the False Prophet will be cast directly into the Lake of Fire. This is because killing them would not be effective. It's this Antichrist that will kill the Two Witnesses.
