What it proves is that scholars do not know the precise date for the Fall of Jerusalem,
Fallacy of division. Just because not everyone knows something, it doesn’t mean no one does. Most modern scholarship recognises that 587 BCE is the correct year, despite various (mostly religious) sources using faulty appeals to tradition for 586 BCE.
The precise date is 29 July 587 BCE. See 586 or 587?
but celebrated WT scholars from the 1870s knew, and it is 607 BCE
Poor doofus doesn’t even seem to know they said it was in 606 BCE until the 1940s. 🤣 When they finally realised there was no ‘year 0’ between 1 BCE and 1 CE, they moved it to 607 BCE to retain their superstitious numerology about 1914.
