and shall deceive many:
as they all of them had their followers, and large numbers of them, whose faith was subverted by them; and who followed their pernicious ways, being imposed upon and seduced by their fair words, specious pretences, and licentious practices.

“From signs, Christ proceeds to the immediate cause of the destruction of Jerusalem; which was, “the abomination of desolation”, or the desolating abomination; or that abominable thing, which threatened and brought desolation upon the city, temple, and nation: by which is meant, not any statue placed in the temple by the Romans, or their order; not the golden eagle which Herod set upon the temple gate, for that was before Christ said these words; nor the image of Tiberius Caesar, which Pilate is said to bring into the temple; for this, if true, must be about this time; whereas Christ cannot be thought to refer to anything so near at hand; much less the statue of Adrian, set in the most holy place, which was an hundred and thirty years and upwards, after the destruction of the city and temple; nor the statue of Titus, who destroyed both, which does not appear: ever to be set up, or attempted; nor of Caligula, which, though ordered, was prevented being placed there: but the Roman army is designed; see ( Luke 21:20 ) which was the (Mmvm Myuwqv Pnk) , “the wing”, or “army of abominations making desolate”, ( Daniel 9:27 ) . Armies are called wings, ( Isaiah 8:8 ) and the Roman armies were desolating ones to the Jews, and to whom they were an abomination; not only because they consisted of Heathen men, and uncircumcised persons, but chiefly because of the images of their gods, which were upon their ensigns: for images and idols were always an abomination to them; so the “filthiness” which Hezekiah ordered to be carried out of the holy place, ( 2 Chronicles 29:5 ) is by the Targum called, ((aqwxyr) , “an abomination”; and this, by the Jewish writers F23, is said to be an idol, which Ahaz had placed upon the altar; and such was the abomination of desolation, which Antiochus caused to be set upon the altar:

“Now the fifteenth day of the month Casleu, in the hundred forty and fifth year, they set up the abomination of desolation upon the altar, and builded idol altars throughout the cities of Juda on every side;” (1 Maccabees 1:54)

And so the Talmudic writers, by the abomination that makes desolate, in ( Daniel 12:11 ) ( 9:27 ) to which Christ here refers, understand an image, which they say F24 one Apostomus, a Grecian general, who burnt their law, set up in the temple. Now our Lord observes, that when they should see the Roman armies encompassing Jerusalem, with their ensigns flying, and these abominations on them, they might conclude its desolation was near at hand; and he does not so much mean his apostles, who would be most of them dead, or in other countries, when this would come to pass; but any of his disciples and followers, or any persons whatever, by whom should be seen this desolating abomination, spoken of by Daniel the prophet:
not in ( Daniel 11:31 ) which is spoken of the abomination in the times of Antiochus; but either in ( Daniel 12:11 ) or rather in ( Daniel 9:27 ) since this desolating abomination is that, which should follow the cutting off of the Messiah, and the ceasing of the daily sacrifice. It is to be observed, that Daniel is here called a prophet, contrary to what the Jewish writers say F25, who deny him to be one; though one of F26 no inconsiderable note among them affirms, that he attained to the end, (yyawbnh lwbgh) , “of the prophetic border”, or the ultimate degree of prophecy: when therefore this that Daniel, under a spirit of prophecy, spoke of should be seen,

standing in the holy place;
near the walls, and round about the holy city Jerusalem, so called from the sanctuary and worship of God in it; and which, in process of time, stood in the midst of it, and in the holy temple, and destroyed both; then

whoso readeth, let him understand:
that is, whoever then reads the prophecy of Daniel; will easily understand the meaning of it, and will see and know for certain, that now it is accomplished; and will consider how to escape the desolating judgment, unless he is given up to a judicial blindness and hardness of heart; which was the case of the greater part of the nation.

John Gill: Then let them which be in Judea
When this signal is given, let it be taken notice of and observed; let them that are in the city of Jerusalem, depart out of it; or who are in any other parts of Judea, in any of the towns, or cities thereof; let them not betake themselves to Jerusalem, imagining they may be safe there, in so strong and fortified a place, but let them flee elsewhere; see ( Luke 21:21 ) and accordingly it is observed, that many did flee about this time; and it is remarked by several interpreters, and which Josephus F1 takes notice of with surprise, that Cestius Gallus having advanced with his army to Jerusalem, and besieged it, on a sudden, without any cause, raised the siege, and withdrew his army, when the city might have been easily taken; by which means a signal was made; and an opportunity given to the Christians, to make their escape: which they accordingly did, and went over Jordan, as Eusebius says F2, to a place called Pella; so that when Titus came a few mouths after, there was not a Christian in the city, but they had fled as they are here bidden to

flee into the mountains;
or any places of shelter and refuge: these are mentioned particularly, because they are usually such; and design either the mountains in Judea, or in the adjacent countries. The Syriac and Persic versions read in the singular number, “into the mountain”; and it is reported that many of them did fly, particularly to Mount Libanus

“five miracles were wrought for our father Jacob, when he went from Beersheba to go to Haran. The first miracle was, that, “the hours of the day were shortened for him”, and the sun set before its time, because his word desired to speak with him.”

They also say,

“that the day in which Ahaz died, was shortened ten hours, that they might not mourn for him; and which afterwards rose up, and in the day that Hezekiah was healed, ten hours were added to it.”

But the meaning here is, that the siege of Jerusalem, and the calamities attending it, should be sooner ended: not than God had determined, but than the sin of the Jews deserved, and the justice of God might have required in strict severity, and might be reasonably expected, considering the aggravated circumstances of their iniquities. A like manner of speech is used by the Karaite Jews, who say,

“if we walk in our law, why is our captivity prolonged, and there is not found balm for our wounds? and why are not, “the days” of the golden and silver kingdom “lessened”, for the righteousness of the righteous, which were in their days?”

“from the time that the temple was destroyed, the wise men, and sons of nobles, were put to shame, and they covered their heads; liberal men were reduced to poverty; and men of violence and calumny prevailed; and there were none that expounded, or inquired, or asked. R. Elezer the great, said, from the time the sanctuary were destroyed, the wise men began to be like Scribes, and the Scribes like to the Chazans, (or sextons that looked after the synagogues,) and the Chazans like to the common people, and the common people grew worse and worse, and there were none that inquired and asked;”

that is, of the wise men there were no scholars, or very few that studied in the law.
