Are you serious?
If the 70th week is 7 years total, in order to be fulfilled during the 70th week, that means these things have to be fulfilled within this 7 year window. IOW we can't claim some of it was fulfilled during the 70th week, and some of it wasn't, and then claim everything is fulfilled in this same 70th week. That would be ludicrous.
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.
If this part is referring to Christ, thus is fulfilled during the 70th week----and in the midst of the week he shall cause the sacrifice and the oblation to cease---then explain how this part was also fulfilled during this same 7 year period----and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate?
In this same 7 years, the 70th week, all of the following have to be fulfilled from start to finish, which means none of it can be fulfilled outside of this 7 years.
And he shall confirm the covenant with many for one week---that has to be fulfilled from start to finish during this 7 years, the 70th week
and in the midst of the week he shall cause the sacrifice and the oblation to cease---that has to be fulfilled from start to finish during this 7 years, the 70th week
and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate---that has to be fulfilled from start to finish during this 7 years, the 70th week
This last part undeniably proves Christ can't be meant anywhere in verse 27.
If you disagree though, show in verse 27 where it indicates some, but not all of the things listed, are fulfilled from start to finish during this 7 years, the 70th week. That would be like claiming some of the things listed in verse 25 are fulfilled from start to finish during the first 69 weeks, but not everything listed in that verse though. No one would do that with verse 25 and 26, in regards to the 69 weeks, so why would anyone do it in verse 27, in regards to everything listed there and the 70th week that is obviously in view in that verse?
Also keep in mind---even until the consummation, and that determined shall be poured upon the desolate---that, too, must be entirely fulfilled once the 70th week has concluded.
