Zechariah 14:1-5

Behold, a day is coming for the LORD when the spoil taken from you (Jerusalem) will be divided in your midst. For I will gather all nations against Jerusalem to battle, and the city will be captured and the houses plundered and the women ravished; and half of the city will be exiled, but the rest of the people will not be cut off from the city. Then the LORD will go forth and fight against those nations, as when He fights on a day of battle. In that day His feet shall stand on the Mount of Olives, which lies before Jerusalem on the east; and the Mount of Olives will be split in half from the east to the west by a very large valley, and half of the mountain will move toward the north and half of it toward the south. [Is 64:1, 2] You will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; and you will flee just as you fled from the earthquake in the days of Uzziah king of Judah. Then the LORD my God will come, and all the holy ones (believers, angels) with Him. [Amos 1:1; Col 3:4; 1 Thess 4:14; Jude 14, 15]
