You raised the contention not myself for I simply quoted COJ's statement that he presents 17 lines of evidence that establishes the chronology of the NB Period consequently the dates 586/7BCE as Neb's 18th year are established for the Fall of Jerusalem. Whether COJ has succeeded in this attempt is open to criticism and is refuted by the research of Rolf Furuli. who has shown that the Chronology for the NB Period is short by at least 20 years.
You continue to miss the point. It's a matter of logic. To provide evidence is different than to undermine another's evidence. COJ is providing affirmative evidence.
Note to readers: Now we come full circle -
In contrast, rather than relying on the chronology of the NB Period in order to fix a date for the Fall of Jerusalem as is the COJ'S method, WT scholars have used the Bible and the biblical '70 years which clearly established that 607 BCE is the only date for the Fall of Jerusalem.
COJ's use of 17 lines of evidence holistically does not disprove 607 BCE because none of these lines of evidence uses any biblical data or reference and that applies to each one of those lines of evidence.
There's the fallback. In the face of overwhelming non-Biblical evidence *for* 587, its all swept aside because "the Bible says differently". And this brings us back to the grammatical issues you have with the scriptures themselves. The Bible agrees with secular history. You can only get to 70 years of desolation by forcing an ungrammatical, noncontextual reading of the scriptures, pushing it into the shape of your obscure religious framework.
