Zechariah 14:4-5

On that day he will stand on the Mount of Olives, east of Jerusalem. The Mount of Olives will split in two, forming a deep valley that runs east and west. Half the mountain will move toward the north, and half will move toward the south. You will run through this mountain valley to the other side, just as you ran from the earthquake when Uzziah was king of Judah. Then the LORD my God will come and all the holy ones with him.
