Verse 20. - And except the Lord had shortened the days, no flesh would have been saved: but for the elect's sake, whom he chose, he shortened the days. St. Matthew's record (Matthew 24:22) differs from that of St. Mark in the omission of the words "the Lord," and the clause "whom he chose." If the time of the siege of Jerusalem had lasted much longer, not one of the nation could have survived; all would have perished by war, or famine, or pestilence. The Romans raged against the Jews as an obstinate and rebellious nation, and would have exterminated them. But "the Lord" shortened the time of this frightful catastrophe, for the elect's sake, that is, partly for the sake of the Christians who could not escape from Jerusalem, and partly for that of the Jews, who, subdued by this awful visitation, were converted to Christ or would hereafter be converted to him We learn from hence how great is the love of God towards his elect, and his care for them. For their sakes he spared many Jews. For their sakes he created and preserves the whole world. Yea, for their sakes, Christ the eternal Son was made man, and became obedient unto death. "All things are yours, and ye are Christ's, and Christ is God's." It may be added that a number of providential circumstances combined to shorten these days of terror. Titus was himself disposed to clemency, and friendly towards Josephus. Moreover, he was attached to Bernice, a Jewess, the sister of Agrippa. All these and other circumstances conspired in the providence of God to "shorten the days."

13:14-23 The Jews in rebelling against the Romans, and in persecuting the Christians, hastened their own ruin apace. Here we have a prediction of that ruin which came upon them within less than forty years after this. Such destruction and desolation, that the like cannot be found in any history. Promises of power to persevere, and cautions against falling away, well agree with each other. But the more we consider these things, the more we shall see abundant cause to flee without delay for refuge to Christ, and to renounce every earthly object, for the salvation of our souls.And except that the Lord had shortened those days,.... Had determined that those days of affliction should be but few, and not last long; that the siege should not be longer continued, and the devastations within and without be prolonged:

no flesh should be saved; there would not have been a Jew left; that nation and race of men must have been utterly destroyed from off the face of the earth:

but for elect's sake, whom he hath chosen; in Christ, unto eternal salvation; who were either then upon the spot, called or uncalled, or that were to spring from in succeeding times:

he hath shortened the days; he hath determined they shall be but few, that a remnant might be saved, and among them his elect; or from whom should descend, such as he had chosen, who should be saved with an everlasting salvation: though the people in general have been given up to blindness and unbelief, yet they are preserved as a distinct people in the world; and in the latter day will be called and converted, and all Israel shall be saved and therefore it was the will of God to shorten those days of affliction, that they might not be entirely cut off, but that a number might be left, as a stock for future ages; See Gill on Matthew 24:22.
