Yeah,who are the "celebrated WT Scholars". And what`s more: You have been attacking the apostates and secular history, because "they can`t make up their mind about which year the temple fell" (as if it had any significance), and at the same time boasting about your "complete Babylonian chronology". So I asked you before, and I`ll ask again: WHERE IS IT! Where is your "complete Babylonian chronology"? Produce it, please, lengths of reigns and all.
There is secular evidence for 607 as you well know for it is based upon the Fall of Babylon and the Return, both these events have testimony from secular sources. the seventy years finds agreement with Josephus, a secular historian and the Fall of Jerusalem in 607 is confirmed biblically and again by Josephus. The foundation of 607 and its calculation is rock solid.
You still don`t understand. That the 70 years would have to relate to the destruction of the Temple, is only required within your JW-theology, which is a "theology" (not really) that even in its foundation is based on making prophecies about when Armageddon will come. But that has nothing to do with the Bible, or the relevant Bible-passages concerning this issue. To any normal person, it is easy to see that the 70 years relate to the period of Babylonian control and power over Judeah. But that would be impossible for you to understand.
