Daniel 9:26: "And after the sixty-two weeks
Messiah (Jesus) shall be cut off, but not for Himself;
And the people (Romans) of the prince who is to come
Shall destroy the city and the sanctuary...."
Yes, Messiah was cut off/crucified (fulfilled)
The Romans then destroyed the temple (fulfilled)
The future prince who is to come (not yet fulfilled) - it gives a clue by saying the people who destroyed the temple (Romans) are of the prince to come, so we know the future prince is someone from the revived Roman empire.
Continuing......
Daniel 9:27: "Then he (roman prince) shall confirm a covenant with many for one week (7 yrs);
But in the middle of the week (3.5 yrs)
he shall bring an end to sacrifice and offering (he will break the contract)
And on the wing of abominations shall be one who makes desolate,
Even until the consummation, which is determined,
Is poured out on the desolate.”
There's a distinction made between "He" in V26 and "he" in V27. A capital letter is always used when God is mentioned, and a lower case for everyone else. This is just additional confirmation, because as I see it the prince in V27 is Antichrist, not Jesus.
None of verse 27 has been fulfilled yet, so it points to a future time.
