Perhaps they are blinded by the Devil or they have not read Josephus or perhaps it betrays some anti-Semitism. Whatever the case I do not care for Josephus plainly states that the seventy years is as I described and provides secular evidence for 607.
They're "blinded by the Devil"? Good grief!
Josephus based his information for this period on the writings of Berossus. The Society doesn't place much credence in the writings of Berossus even though he concurs with Daniel that captives were taken in Nebuchadnezzar's first (accession) year. The Society makes a number of references to Berossus getting his information from that nasty Seleucid Period (snicker), as if that makes the information unreliable. (They say it is too far removed from the actual events). But you are saying that Josephus, basing his information on the same 'unreliable' source, even further removed from the original events, provides evidence for the Society's interpretations.
All of Josephus' references to the seventy years can be reconciled with the fact that Jerusalem was destroyed in 587. Additionally, he is in agreement that captives were first taken about 70 years prior to their return from Babylon (in Nebuchadnezzar's accession year).
According to Jeremiah 52:29, there were only 832 exiles taken in Nebuchadnezzar's 18th year anyway (though 2 Kings 24:14 indicates about 10,000+ were taken) According to Jeremiah 52:28, 3023 Jews were taken 11 years prior, and if Jeremiah is consistent, then this may reflect a much larger number also. You would have us believe that when this group of Jews arrived at Babylon in Nebuchadnezzar's 18th year, they met up with the other 3023 (or more) exiles from Nebuchadnezzar's 7th year, and said "Hey chaps, we've decided not to bother counting the eleven years you've been here" - very unlikely, even if they could speak English. (Not to mention the captives that were taken as booty in Nebuchadnezzar's accession year earlier still.) Further, if there were more exiles taken than Jeremiah bothered to mention, then his omission also provides no basis for your previous allegation that captives were not taken in Nebuchadnezzar's accession year.
