Zechariah 14:4 And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.

But who would not be surprised at the fulfillment of a prophecy which revealed that the Jewish people would undergo these sufferings in the days of the Lord? For as soon as Jesus our Lord and Saviour had come and the Jews had outraged Him, everything that had been predicted was fulfilled against them without exception 500 years after the prediction: from the time of Pontius Pilate to the sieges under Nero, Titus and Vespasian they were never free from all kinds of successive calamities, as you may gather from the history of Flavius Josephus.... For after the coming of our Saviour Jesus Christ, their city, Jerusalem itself, and the whole system and institutions of the Mosaic worship were destroyed; and at once they underwent captivity in mind as well as body, in refusing to accept the Saviour and Ransomer of the souls of men, Him Who came to preach release to those enslaved by evil dæmons, and giving of sight to those blind in mind. ~ Eusebius (4th century historian), The Proof of the Gospel, trans.

"That the Mount of Olives shall be divided, half of it to the east and towards the sea, a very great chasm and half of it shall lean towards the north, and half of it towards the south," it possibly shews the expression of the Church throughout the whole inhabited world, for it has filled the east, and the western and eastern nations; it stretches to the western sea, and the isles therein; yea, it has reached to west and south, and to north and north-east. On all sides and everywhere the Church figuratively called the Olive of the Lord is planted. ~ Eusebius (4th century historian), The Proof of the Gospel, trans. W. J. Ferrar, 2 vols. in 1 (Grand Rapids, MI: Baker Books, 1981), 2:31 (289d).
