As he approached the city and saw it, he wept over it, and said, "If you yourself only knew today the conditions of peace! But as it is, they are hidden from you. For a time is coming upon you when your enemies will throw up earthworks about you and surround you and shut you in on all sides, read more.
and they will throw you and your children within you to the ground, and they will not leave one stone upon another within you because you did not know when God visited you!"

Luke 21:20-24

But when you see Jerusalem being surrounded by armies, then you must understand that her devastation is at hand. Then those who are in Judea must fly to the hills, those who are in the city must get out of it, and those who are in the country must not go into it, for those are the days of vengeance, when all that is written in the Scriptures will be fulfilled. read more.
But alas for women who are with child at that time, or who have babies, for there will be great misery in the land and anger at this people. They will fall by the edge of the sword, and be carried off as prisoners among all nations, and Jerusalem will be trampled under foot by the heathen, until the time of the heathen comes.

Revelation 16:12-21

The sixth emptied his bowl upon the great river Euphrates, and its waters dried up to make the way ready for the kings from the east. Then I saw three foul spirits like frogs emerge from the mouth of the dragon and from the mouth of the animal and from the mouth of the false prophet. They are demon spirits that perform wonders, and they go out to the kings all over the world to muster them for battle on the great Day of God Almighty. read more.
(See, I am coming like a thief! Blessed is he who keeps awake, and keeps hold of his clothes, so that he will not have to go naked and be put to shame!) So they mustered the kings at the place called in Hebrew Armageddon. The seventh emptied his bowl upon the air, and a loud voice came out of the temple from the throne, saying, "It is all over!" Then there were flashes of lightning, rumblings and peals of thunder, and there was a great earthquake; there has never been such an earthquake since man first existed upon the earth, it was so great. The great city broke into three pieces, the cities of the heathen fell, and God remembered to give mighty Babylon the cup of the wine of his fierce anger. Every island vanished, the mountains disappeared, huge hailstones of immense weight fell on mankind from heaven, and men reviled God because of the plague of hail, the plague of it was so terrible.

Revelation 20:7-10

When the thousand years are over, Satan will be released from his prison, and will go out to lead astray the heathen in the four corners of the earth, Gog and Magog, and to muster them for battle, in numbers like the sand of the seashore. They came up on the broad plain of the earth and surrounded the encampment of God's people, and the beloved city. Then fire came down from heaven and consumed them, read more.
and the devil who led them astray was flung into the fiery, sulphurous lake, where the animal and the false prophet were, there to be tortured day and night forever and ever.
