First off ... there has been confusion about 586-590 ... certainly. But there is NO CONFUSION about 607 BC - because it is a made up date. All scholars (not you), archeologists, historians, religious leaders, and even the BIBLE agree that 607 BC is not even in contention.
Second, the only time I get confused is when I read the Society's literature.
A clear and almost unanimous picture comes into focus as soon as one ditches the mismatched dates of the Society's literature. This is why my pioneer/missionary book study conductor and his pioneer assistant cannot explain 607 BC.
The Society's chronology is like a bad supermarket tabloid. Some of it is fact, some of it is rumor, some of it is downright lies. The trick with a tabloid is to determine what stories are real and what are lies. WT Chronology is nothing different.
I am reminded of what my non-JW father used to tell me ... once you start with one lie ... you then need to tell tons of other little lies to keep the original lie intact.
607 is nothing more than this. Besides ... there have been 30+ page threads on this forum where you have had to admit you were wrong. I guess you're hoping that the newbies on here won't find it?
