Zechariah 14:4-5

4In 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 in its middle from east to west by a very large valley, so that half of the mountain will move toward the north and the other half toward the south. 5You 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 before the 3earthquake in the days of Uzziah king of Judah. 4Then the Lord, my God, will come, and all the holy ones with 5Him!
