A quote from William Kelly:
[quoting]
" "For then" (our Lord says) "shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be." Many, I am aware, apply this to the destruction of Jerusalem by Titus, and to the great calamities that then broke up the Jews. But there is one essential point of difference that ought not to be overlooked. The Jewish people were
not delivered then. Whereas, when Daniel's prophecy is accomplished, they are, and must be, delivered - not at a subsequent epoch, but at
that time. If Daniel is a true prophet (and no one who reveres the Lord, and rightly weighs His words, will question it), it is not that his prophecy failed, but that it remains to be fulfilled. Our Lord distinctly and positively quotes from that prophecy, and from the very chapter (Dan. 12) we are considering. And what does He connect with Israel's deliverance? His own coming as the Son of man from heaven. Who can say that this has been? The Romans, instead of being broken down in the time of Titus, were allowed to enslave the Jews. These were not then delivered, nor, up to the present moment, have they ever been the masters of their own temple, nor allowed to be in their own land, even as ordinary men. If there is one race more peculiarly proscribed in the Holy Land, it is the Jewish. The Turks, the present possessors of it, have held it for many a long year; and all, whether Crusaders or Saracens, have agreed to shut out the Jews. So that there has been nothing like the Son of man coming to deliver Israel. Michael has
not stood up for them in that sense yet.
"Thus, what I have shown from the Old Testament is amply confirmed by the New. Prophet after prophet, all distinctly furnish the same outline, i.e. a time of trouble, such as never was before, followed immediately by a deliverance such as Israel has never yet enjoyed. It is perfectly plain, as we all believe, that these prophecies are of God, that it is only a question of waiting God's time for Himself to accomplish them to the very letter. As our Lord says in this same chap. 24 of Matthew, "Heaven and earth shall pass away, but My words shall not pass away." It is not only that the general strain is true, but not one jot nor one tittle shall pass till all be fulfilled. The notion that God has cast away His people, Israel, because He is now in mercy filling up the blank season of their rebellion against the Lord Jesus and the gospel, is distinctly treated in Romans 11, as the offspring of Gentile conceit. For not only is God able to graft the natural branches into their own olive tree, but when the fulness of the Gentiles is come in, all Israel shall be saved according to clear prophecy. They are to become objects of divine saving mercy at the end, as we now; only in their case it will be in their land. "And the Redeemer shall come to Zion," etc.
"If this be so, we have an important key to the prophecy of Daniel. Although the destruction of Jerusalem by the Romans was so near, yet the Lord distinctly looks onward to another time. And what makes it the more remarkable is, that one evangelist does give us the destruction of Jerusalem by the Romans, but also
distinguishes it from this future time of trouble. In Luke 21 is the chief reference of a positively prophetic kind to the Roman destruction of Jerusalem. And mark the difference of the language: "And when ye shall see Jerusalem compassed about with armies." Not a word about the abomination of desolation standing in the holy place. Luke passes over this entirely, and introduces what Matthew does not mention - Jerusalem encompassed with armies. "When ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out," etc. That is, the Lord prescribes exactly the same course to be taken by the Jews in Jerusalem, whether at the approaching sack of the city by the Romans (as in Luke), or at the future desolation that should fall upon it (as in Matthew). So far there was an analogy between the two things: the godly were to flee away; they were not to trust to vain hopes of deliverance through some pretended Messiah, but were to know from the lips of the Lord Himself, that Jerusalem was to fall under the hand of the Gentiles. If any wanted to escape, it must be outside Jerusalem. "And let not them that are in the countries enter thereinto." No matter what people may say of the necessity of any keeping their feast, their path of safety is to avoid Jerusalem. There is no deliverance for Israel yet. "For these be the days of vengeance, that all things which are written may be fulfilled."
"Luke, it will be observed, does not say, This is the time of trouble, such as was not since the beginning of the world. There is the most surprising perfectness of expression. […]"
