Zechariah 14:3-4

New Catholic Bible

³ Then the Lord will go forth and fight against those nations, fighting as on a day of battle. ⁴ On that day his feet will stand on the Mount of Olives, which lies to the east of Jerusalem. The Mount of Olives will be split in two from east to west by an immense valley, so that half of the mountain will move north and the other half will move south.
