“Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.
There shall not be left here one stone upon another – At the time this was spoken, no event was more improbable than this. The temple was vast, rich, splendid. It was the pride of the nation, and the nation was at peace. Yet in the short space of 40 years all this was accomplished exactly. Jerusalem was taken by the Roman armies, under the command of Titus, 70 a.d. The account of the siege and destruction of the city is left us by Josephus, a historian of undoubted veracity and singular fidelity. He was a Jewish priest. In the wars of which he gives an account, he fell into the hands of the Romans, and remained with them during the siege and destruction of the city. Being a Jew, he would of course say nothing designed to confirm the prophecies of Jesus Christ; yet his whole history appears almost like a running commentary on these predictions respecting the destruction of the temple. The following particulars are given on his authority:
After the city was taken, Josephus says that Titus “gave orders that they should now “demolish the whole city and temple,” except three towers, which he reserved standing. But for the rest of the wall, it was laid so completely even with the ground by those who “dug it up from the foundation,” that there was nothing left to make those believe who came hither that it had ever been inhabited.” Maimonides, a Jewish writer, has also recorded that “Terentius Rufus, an officer in the army of Titus, with a plowshare tore up the foundations of the temple, that the prophecy might be fulfilled, ‘Zion shall be plowed as a field,'” Micah 3:12. This was all done by the direction of divine Providence. Titus was desirous of preserving the temple, and frequently sent Josephus to the Jews to induce them to surrender and save the temple and city. But the prediction of the Saviour had gone forth, and, notwithstanding the wish of the Roman general, the temple was to be destroyed. The Jews themselves first set fire to the porticoes of the temple. One of the Roman soldiers, without any command, threw a burning firebrand into the golden window, and soon the temple was in flames. Titus gave orders to extinguish the fire; but, amid the tumult, none of the orders were obeyed. The soldiers pressed to the temple, and neither fear nor entreaties, nor stripes could restrain them. Their hatred of the Jews urged them on to the work of destruction, and thus, says Josephus, the temple was burned against the will of Caesar. – Jewish Wars, b. 6 chapter 4, section 5-7….

…am Christ – I am the Messiah. See the notes at Matthew 1:1. The Messiah was expected at that time, Matthew 2:1-2. Many would lay, claims to being the Messiah, and, as He was universally expected, multitudes would easily be led to believe in them. There is abundant evidence that this was fully accomplished. Josephus informs us that there were many who pretended to divine inspiration; who deceived the people, leading out numbers of them into the desert. “The land,” says He “was overrun with magicians, seducers, and impostors, who drew the people after them in multitudes into solitudes and deserts, to see I the signs and miracles which they promised to show by the power of God.” Among these are mentioned particularly Dositheus, the Samaritan, who affirmed that He was Christ; Simon Magus, who said He appeared among the Jews as the Son of God; and Theudas, who persuaded many to go with him to the river Jordan, to see the waters divided. The names of 24 false Messiahs are recorded as having appeared between the time of the Emperor Adrian and the year 1682…

…Nation shall rise against nation, and kingdom against kingdom – At Caesarea the Jews and Syrians contended about the right to the city, and twenty thousand of the Jews were slain. At this blow the whole nation of the Jews was exasperated, and carried war and desolation through the Syrian cities and villages. Sedition and civil war spread throughout Judea; Italy was also thrown into civil war by the contests between Otho and Vitellius for the crown.

And there shall be famines – There was a famine foretold by Agabus Acts 11:28, which is mentioned by Tacitus, Suetonius, and Eusebius, and which was so severe in Jerusalem, Josephus says, that many people perished for want of food, Antiq. xx. 2. Four times in the reign of Claudius (41-54 a.d.) famine prevailed in Rome, Palestine, and Greece.

Pestilences – Raging epidemic diseases; the plague, sweeping off multitudes of people at once. It is commonly the attendant of famine, and often produced by it. A pestilence is recorded as raging in Babylonia, 40 a.d. (Josephus, Antiq. xviii. 9. 8); in Italy, 66 a.d. (Tacitus 16. 13). Both of these took place before the destruction of Jerusalem.

Earthquakes – In prophetic language, earthquakes sometimes mean political commotions. Literally, they are tremors or shakings of the earth, often shaking cities and towns to ruin. The earth opens, and houses and people sink indiscriminately to destruction. Many of these are mentioned as preceding the destruction of Jerusalem. Tacitus mentions one in the reign of Claudius, at Rome, and says that in the reign of Nero the cities of Laodicea, Hierapolis, and Colosse were overthrown, and the celebrated Pompeii was overwhelmed and almost destroyed by an earthquake, Annales, 15. 22. Others are mentioned as occurring at Smyrna, Miletus, Chios, and Samos. Luke adds, “And fearful sights and great signs shall there be from heaven,” Luke 21:11. Josephus, who had probably never heard of this prophecy, and who certainly would have done nothing designedly to show its fulfillment, records the prodigies and signs which He says preceded the destruction of the city.

A star, says he, resembling a sword, stood over the city, and a comet that continued a whole year. At the feast of unleavened bread, during the night, a bright light shone round the altar and the temple, so that it seemed to be bright day, for half an hour. The eastern gate of the temple, of solid brass, fastened with strong bolts and bars, and which had been shut with difficulty by twenty men, opened in the night of its own accord. A few days after that feast, He says, “Before sunsetting, chariots and troops of soldiers in their armor were seen running about among the clouds, and surrounding of cities.” A great noise, as of the sound of a multitude, was heard in the temple, saying, “Let us remove hence.” Four years before the war began, Jesus, the son of Ananus, a plebeian and a husbandman, came to the feast of the tabernacles when the city was in peace and prosperity, and began to cry aloud, “A voice from the east, a voice from the west, a voice from the four winds, a voice against Jerusalem and the holy house, a voice against the bridegroom and the brides, and a voice against this whole people!” He was scourged, and at every stroke of the whip He cried, “Woe, woe to Jerusalem!” This cry, Josephus says, was continued every day for more than seven years, until He was killed in the siege of the city, exclaiming, “Woe, woe to myself also!” – Jewish Wars, b. 6 chapter 9, section 3.
