Zechariah 14:4-9

4 On that day His feet will stand on the Mount of Olives,a which faces Jerusalem on the east. The Mount of Olives will be split in half from east to west, forming a huge valley, so that half the mountain will move to the north and half to the south.
5 You will flee by My mountain valley,b for the valley of the mountains will extend to Azal. You will flee as you fledc from the earthquake in the days of Uzziah king of Judah.d Then the Lord my God will come and all the holy ones with Him.ef
6 On that day there will be no light; the sunlight and moonlightg will diminish.hi
7 It will be a day known [only] to Yahweh,j without day or night, but there will be light at evening.
8 On that day living water will flow out from Jerusalem,k half of it toward the eastern seal and the other half toward the western sea,m in summer and winter alike.
9 On that day Yahweh will become king over all the earthn-Yahweh alone, and His name alone.o
