Greetings!
I know it isn't necessary for the majority of readers/visitors/participants on this site but for those that may be lurking this thread, I thought that I would just point out regarding the excerpted Society's explanation above.
The 70 years of servitude/desolation referred to in Chronicles and Jeremiah is NOT INCONSISTENT with an actual destruction date of 596/7 BCE of Jerusalem.
If one reads both scriptures cited in the article in context then one easily sees that in Chronicles it is plainly referring to the first deportation of captives from Jerusalem to Babylon and in Jeremiah it is referring to the Babylonian warring and subjugation of all of the lands around Judea. Both of these events occurred in the early reign of Nebuchadrezzar/Nebuchanezzar between 607-604 BC in his campaign against this area. The first deportation of the conquered included the notables of the city of Jerusalem including Daniel and the king Jehoiakim. Nebuchadrezzar set up Zedikiah as a puppet King. Eleven (11) years later Zedekiah rebelled and so about 593 Babylon renewed its subjugation of Judea ultimately resulting in the beseiging of Jerusalem and razing of most of the city in 587/6.
The point is that when Chronicles or Jeremiah or Daniel refer to the 70 years prophecy/references ("at Babylon') these are correct BUT the Society wants the membership to believe that this means 70 years since the DESTRUCTION of the city of Jerusalem but what the scriptures actually refer to is the beginning of the bondage or subjugation to Babylonian/Chaldean rule.
