Zechariah 14:4

4 At that time he will stand on the Mount of Olives, to the east of Jerusalem. Then the Mount of Olives will be split in two from east to west by a large valley. Half of the mountain will move northward, and half of it southward.

Zechariah 14:4 In-Context

2 The Lord will bring all the nations together to make war on Jerusalem. The city will be taken, the houses looted, and the women raped. Half of the people will go into exile, but the rest of them will not be taken away from the city.
3 Then the Lord will go out and fight against those nations, as he has fought in times past.
4 At that time he will stand on the Mount of Olives, to the east of Jerusalem. Then the Mount of Olives will be split in two from east to west by a large valley. Half of the mountain will move northward, and half of it southward.
5 You will escape through this valley that divides the mountain in two. You will flee as your ancestors did when the earthquake struck in the time of King Uzziah of Judah. The Lord my God will come, bringing all the angels with him.
6 When that time comes, there will no longer be cold or frost,
