Zechariah 14:6
“And it shall come to pass in that day, that the light shall not be clear, nor dark:”
And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the Lord my God shall come, and all the saints with thee.
And it shall come to pass in that day, that the light shall not be clear, nor dark:
But it shall be one day which shall be known to the Lord, not day, nor night: but it shall come to pass, that at evening time it shall be light.
And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
