Zechariah 14:4-5

4On that day His feet will 1stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be 2split 3in its middle from east to west forming a very large valley. Half of the mountain will move toward the north, and the other half toward the south. 5And you will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; yes, you will flee just as you fled from the 4earthquake in the days of Uzziah king of Judah. 5Then the Lord, my God, will come, and all the holy ones with 6Him!
