Missed the point completely. In fact, I'm not exactly sure what you are arguing. Yes, 17 is the number. Yes, they are lines of evidence. The evidence provided isn't against 607 in as much as its for 587. It's an important distinction. There could be a 17 independent lines of evidence *against* 607, and each could arrive at a different date. Each line arguing a different date is a line AGAINST 607. But if all the lines agreed on a single date, that's an entirely different story. It's evidence FOR 587. Yes that disproves 607, by it raises the confidence level for 587 to near certainty.
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.
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.
