Zechariah 14:4-8

4On that day his feet will stand on the Mount of Olives, east of Jerusalem. And the Mount of Olives will split apart, making a wide valley running from east to west. Half the mountain will move toward the north and half toward the south.

5You will flee through this valley, for it will reach across to Azal. Yes, you will flee as you did from the earthquake in the days of King Uzziah of Judah. Then the Lord my God will come, and all his holy ones with him.

6On that day the sources of light will no longer shine,

7yet there will be continuous day! Only the Lord knows how this could happen. There will be no normal day and night, for at evening time it will still be light.

8On that day life-giving waters will flow out from Jerusalem, half toward the Dead Sea and half toward the Mediterranean, flowing continuously in both summer and winter.
