Zechariah 14:4-5

And in that day His feet will stand on the Mount of Olives, Which faces Jerusalem on the east. And the Mount of Olives shall be split in two, From east to west, Making a very large valley; Half of the mountain shall move toward the north And half of it toward the south. Then you shall flee through My mountain valley, For the mountain valley shall reach to Azal. Yes, you shall flee As you fled from the earthquake In the days of Uzziah king of Judah. Thus the LORD my God will come, And all the saints with You.
