No! Daniel 9:27 is not talking about the 'Abomination of Desolation'!The Book of Daniel describes something called 'the abomination that maketh desolate':
Daniel 11:31 - And arms shall stand on his part, and they shall pollute the sanctuary of strength, and shall take away the daily sacrifice, and they shall place the abomination that maketh desolate.
Daniel 12:11 - And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days.
What is it? Has it happened already?
According to Daniel 9:27, the Abomination of Desolation happens in the 'midst of the week':
Daniel 9:27 - And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
Isn't that when the Crucifixion happened?
Rather, it is talking about abominations in general - the many [various] abominations in/of Israel.
Daniel 11:31 is specifically referring to the one-and-only real-and-true actual bona fide [prophetic] 'Abomination of Desolation'.
Daniel 12:11 is making specific reference to the 'Abomination of Desolation' as referred to in Daniel 11:31.
Daniel 9:27 is not talking about the 'Abomination of Desolation' as referred to in Daniel 11:31.
Just because some form and use of the word 'abomination' exists in a verse together with some form and use of the word 'desolate' does not mean it is referring to the one-and-only real-and-true actual bona fide [prophetic] 'Abomination of Desolation' - which occurred in 167 B.C.
Also - the words you bolded and underlined in the Daniel 9:27 verse above are not included within the 'midst of the week' statement in that same verse - the scope of which is [only] the words between the colon and the first/next comma after it.
Yes - the Crucifixion occurred 'in the midst of the week'; however, it had absolutely nothing to do with the one-and-only real-and-true actual bona fide [prophetic] 'Abomination of Desolation' - which occurred in 167 B.C.
