Scholar,
Maybe you can help me on this. I hope you can. It's been a while since I have studied this subject matter. And I don't have a volume of Insight On The Scriptures available to me right now to look this up.
We all understand that Babylon fell in 539 BC. All non-JW historians tell us that Jerusalem fell about 48 years earlier. However, JWs believe this took place not 48 years earlier, but 68 years earlier.
To account for these extra 20 years, I believe JWs say that the Babylonian kings who ruled between the time of Jerusalem's fall to Babylon and Babylon's fall to Cyrus actually ruled about 20 years longer than Babylon's historical records are commonly understood to say that they did.
To the reign of what king or kings do JWs now assign these extra 20 years?
Wherever you assign these extra 20 years, why have no Babylonian business documents been found dated to any of them? Or have they?
After all, haven't many such documents been found dated to every year of every known Babylonian king's reign during this time period, as the years of their reigns are now commonly understood?
Thanks for your help.
