Daniel 9:27
27 And he will make a firm covenant with the many for one week, but in the middle of the week he will put a stop to sacrifice and grain offering; and on the wing of abominations will come one who makes desolate, even until a complete destruction, one that is decreed, is poured out on the one who makes desolate.

We are not told the content of this covenant, but it is probably through this agreement that the territorial integrity of Israel is guaranteed and the Temple is rebuilt in Jerusalem. Relations between the two parties rapidly deteriorate, however, and after 3 1/2 years the antichrist commits the damnable act of what both Daniel and Jesus call the "abomination of desolation:"

Matthew 24:15-16
15 Therefore when you see the ABOMINATION OF DESOLATION which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand),16 then let those who are in Judea flee to the mountains;

Paul describes this same event in further detail:

2 Thessalonians 2:3b-4
...The man of lawlessness is revealed, the son of destruction, who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.¹

This damnable act by the "man of lawlessness" in the holy sanctuary of the Temple in Jerusalem is a critical moment in prophecy. This is probably the one act the antichrist does that causes the Jewish people to make a wholesale defection from him. They may have gone along with him as a wonder worker of peace and prosperity at the beginning, some even thinking he was the Messiah. However, when he claims to be god, this is more than the Jews can stand, and they revolt against him almost to a man.  ... Jesus warns the Jews, especially the believing Jews, to flee from Jerusalem into the wilderness. Many Israelites do flee from the wrath of the Serpent (Satan, represented by the antichrist) as described in Revelation:
