The WTS suggestion that ancient Jerusalem fell in 607 BCE is nonsensical and fraudulent given the information from archeological findings and the chronological dating within the bible itself.
Out of those all of these resources it makes the probability of the year of 586 BCE as being correct.
The WTS stood and uphold 607 for so long because it supports 1914 which the WTS still upholds to this day.
Maybe the WTS should have upheld Jesus's statement that no one knows of the time not even he and obeyed the counsel by him to his faithful followers to not set a time upon God's own sacred time ???
But then again the WTS would not have such compelling and alluring information to proliferate the literature they published.
