Thank you for the reply it is an interesting view of prophecy.
My first questions would be to ask “why do you believe that the final week of the prophecy would be disconnected with the previous 69 and way into the future?” and “what is the reason to assume that verse 27 is about an Anti-Christ” I tried reading the verses multiple times in different translations and cannot find any logical reason for why it is into the future. We must also remember that Jesus is the literal sacrifice that all other sacrifices pointed towards. His death would be the reason all sacrifices cease. The calculations in the post show Jesus’ death would perfectly line up with this prophecy as I have explained it.
My next point would be on the idea of a literal nation of Israel. Many people have fallen into the trap that Israel is a (or maybe we should say the) literal country with complete borders and a political system even though this was formed just after the second world war. the New Testament, especially in Pauls writings, refers to a group of believers in Christ as true Israel not a literal place. Ideas of this can be seen in verse such as Romans 2:28 ”For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 29but he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.”
And, Galatians 4:26 “26But Jerusalem which is above is free, which is the mother of us all. 27For it is written,” (I’d suggest reading the whole chapter to understand those quotes).
I hope this gives you a better understanding of my post
