Zechariah 14:5 in the King James Version
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.
Context
4 His feet will stand in that day on the Mount of Olives, which is before Jerusalem on the east; and the Mount of Olives will be split in two from east to west, making a very great valley. Half of the mountain will move toward the north, and half of it toward the south.
5 You shall flee by the valley of my mountains, for the valley of the mountains shall reach to Azel. Yes, you shall flee, just like you fled from before the earthquake in the days of Uzziah king of Judah. The LORD my God will come, and all the holy ones with you.
6 It will happen in that day that there will not be light, cold, or frost.
