Isaiah 64:2

“Therefore thus I will do to you, O Israel; Because I will do this to you, Prepare to meet your God, O Israel.”

The mountains will melt under Him, And the valleys will be split, Like wax before the fire, Like water poured down a steep place.

And in that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley so that half of the mountain will move toward the north and the other half toward the south.
