Zechariah 14:4-9

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. On that day there will be no light, cold, or frost. There will be no other day like it, and the LORD knows when it will come. There will be no day or night; even at evening it will still be light. At that time fresh water will flow from Jerusalem. Half of it will flow east to the Dead Sea, and half will flow west to the Mediterranean Sea. It will flow summer and winter. Then the LORD will be king over the whole world. At that time there will be only one LORD, and his name will be the only name.
