Zechariah 14:4-8

4And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem toward the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, — a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.

5And ye shall flee [by] the valley of my mountains; for the valley of the mountains shall reach unto Azal: ye shall even flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah. And Jehovah my 1God shall come, [and] all the holy ones with thee.

6And it shall come to pass in that day, [that] there shall not be light; the shining shall be obscured.

7And it shall be one day which is known to Jehovah, not day, and not night; and it shall come to pass, at eventide it shall be light.

8And it shall come to pass in that day [that] living waters shall go out from Jerusalem; half of them toward the eastern sea, and half of them toward the hinder sea: in summer and in winter shall it be.
