Try not to be any sillier than you can avoid. Mixing multiple meanings of the same word is one of the lamest debating tricks around. You can do better than that.
At what, giving you things that test your 'bullbiscut' detectors ability to handle any/all truths that come 'a persons way'? An imperfect reader has a better chance at discovering 'hidden things' than a reader who already has 'perfect knowledge'. Perfect knowledge is also known as a wall or a blind alley.
Having the Scriptures determine how the verses are to be taken should be the preferred method over taking the reasoning of a man or even a group of 'learned men' as being the definitive solution to a riddle/mystery surround a passage or doctrine. If the 'accepted use' for cut-off is applied to a verse from the 70 weeks prophecy then there is a change 'implied' if it was not for several other references that correct that 'possible error in thinking'. If the correct use is almost exclusive to a one use type of thing then it would seem like that sort of knowledge would only be available to a through examination of the use of that word compared to a 'most likely meaning' judgment.
Nobody would think/support an examination of all the OT mentions of Babylon is needed even though the NT mentions a Babylon that is obviously a different place. If such an undertaking was done and just one or two or three references applied would that make the 99.97% of the trails that were true dead ends, would that justify the time needed for such an extensive undertaking. If that isn't worth it then if all references to Babylon that involved punishment were about Satan's Babylon then would the search be worth the effort even though many were still in context and being a reference to Neb and his Babylon.
Heb:12:2:
Looking unto
Jesus the author and finisher of our faith;
who for the joy that was set before him endured the cross,
despising the shame,
and is set down at the right hand of the throne of God.
