Zechariah 14:4-8

4On that day his feet shall stand on the Mount of Olives that lies before Jerusalem on the east, and the Mount of Olives shall be split in two from east to west by a very wide valley, so that one half of the Mount shall move northward, and the other half southward.

5And you shall flee to the valley of my mountains, for the valley of the mountains shall reach to Azal. And you shall flee as you fled from the earthquake in the days of Uzziah king of Judah. Then the Lord my God will come, and all the holy ones with him.

6On that day there shall be no light, cold, or frost.

7And there shall be a unique day, which is known to the Lord, neither day nor night, but at evening time there shall be light.

8On that day living waters shall flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea. It shall continue in summer as in winter.
