For those days shall be tribulation, such as there hath not been the like from the beginning of the creation. These expressions are very remarkable. To begin with, the tribulation would be so unexampled and so severe that the days themselves would be called "tribulation."
They would be known ever after as "the tribulation.'" There never had been anything like them, and there never would be again. Neither the Deluge, nor the destruction of the cities of the plain, nor the drowning of Pharaoh and his host in the Red Sea, nor the slaughter of the Canaanites, nor the destruction of Nineveh, or of Babylon, or of other great cities and nations, would be so violent and dreadful as the overthrow of Jerusalem by Titus.
All this is confirmed by Josephus, who says, speaking of this overthrow, "I do not think that any state ever suffered such things, or any nation within the memory of man." St. Chrysostom assigns the cause of all this to the base and cruel treatment of the Son of God by the Jews.
The destruction of their city and their temple, and their continued desolation afterwards, were the lessons by which the Jews were to be taught that the Christ had indeed come, and that this was the Christ whom they had crucified and slain.
