The context in Dan 9 is the Prince whose people destroy the cityy and sanctuary. He is the one who is here:
Dan 9:25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
Dan 9:26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
Dan 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.
This is the one who in the NT is called the abomination of desolation and of course that is not Jesus.
Mathew 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place,
Just to make it clear, I also do not believe that Jesus calling His own crucifixion "the abomination of desolation" in this verse.
I also do not believe that He is referring to anything that occurred within that seventy week period.
So what did Daniel speak of that could be called "the abomination of desolation"?
Our passage certainly mentions desolations, and even abominations (sins), but the answer is not here but in Daniel 11.
The whole life career of Antiochus is described in detail in this chapter, including his act of placing the "abomination that maketh desolate" (v.31) in the sanctuary.
This was a statue of Jupiter Olympus.
Anyway, your thoughts are about Daniel 9:25-27, and who the pronoun "he" represents in v.27.
You suggest that it should represent the prince.
The two main possibilities i see in v.26 for the pronoun are the people (pronoun would be "they") and the Messiah.
The prince? Well perhaps if you really wanted it to be.
In any case v. 26 definitely refers an event that I think falls outside the seventy week time.
Daniel did not name the passage "Daniel's 70 weeks", and is at liberty to do that.
So that leaves us looking at what "He" did in order to establish who "He" is.
The possibilities I consider is the Messiah and the prince, because the people require a plural pronoun.
Lets consider the three actions in v.27:
1. He shall confirm the covenant with many for one week.
Jesus brought many (not all) into a true covenant relationship with God.
His ministry was to the Jews, as was the ministry of the Apostles at first.
This time period was close on 7 years.
The case for the prince: He destroys the city and sanctuary, brings only desolations, described as a flood,
Daniel 11:30 describes him as having "indignation against the holy covenant",--so not good.
2. In the midst of the week he shall cause the sacrifice and oblation to cease.
Well we seem to be stuck on that one.
I would maintain that unless Jesus was not the final sacrifice for sin, He really did that.
...And for the prince: The prince is said in Daniel 11:31 to have taken away the daily sacrifice, and you may like that, but I think it is a different matter.
3 .For the overspreading of abominations he shall make it desolate.
This is referring to the sacrifice and oblation here, and although I think the reference is to Jesus for making it desolate in the spiritual sense, it could be said that the prince kind of teams up with Him here, for smashing the place to bits and humiliating the people.
The final case I make for the Messiah is He makes the whole passage make sense without inserting that ridiculous "gap".
The last line (even until the consummation, and that determined shall be poured upon the desolate), can go as far into the future as it does.
We are not told that it must be a single event, or that it must fit into the weeks.
