It must be my turn to reply to scholar's nonsense!
1. A precise calender date for the Fall of Jerusalem
How many times do you have to have it explained to you why it cannot be determined in which calendar year Jerusalem fell? The bible is ambiguous about which calendar to use. Use the Nisan calendar and you get 25 August 587 BC or use the Tishri calendar and get 15 August 586 BC. Compare this to the Babylonian chronicle which pinpoints the first capture of Jerusalem as 15/16 March 597 BC in Nebuchadnezzar's seventh year.
2. A definite calender year for the beginning and end of the seventy years
The bible itself gives the original seventy year prophecy a number of end dates. The Chronicler has it fulfilled in the restoration under Cyrus (Ezra 1:1). Zechariah extends these seventy years to continue up until the reign of Darius I around 519 - 516 BC (strangely enough about seventy years after the real date for the destruction of the temple). In the fictional chronology of Daniel, chap 9 is set before Cyrus. The real author wrote long after the Chronicler and Zechariah and rejects both their interpretations in favour of 'seventy weeks of years'.
3. The length of the seventy years and whether it is literal or symbolic
I personally think the original prophecy was a symbolic seventy years which was meant to signify a lifetime. (Holladay, Jeremiah I p668-669)
4. The end of the Assyrian World Power
Ninevah was finally destroyed by the Medes and Babylonians in 612 BC. The last Assyrian king disappeared from history in 609 BC with the destruction of Harran. Unfortunately for so-called Watchtower scholars they have to move these events 20 years back in time. This is impossible as texts such as astronomical diary BM32312 and the Akitu Chronicle BM86379 give the date of the battle of Hirit in Shamash-shamukin's 16th year as the absolute date of 651 BC. Business documents, The Uruk King list and the Akitu chronicle then give the following years for the reigns of these kings at Babylon:
Shamashshumukin 20 years 667 - 648
Kandalanu 22 years 647 - 626
Nabopolassar 21 years 625 - 605
So the Watchtower has to dismiss the absolute date 651 BC. Not very scholarly is it?
5. A king list for the Divided Monarchy
I think others on this board have again shown you time and again that the ambiguity in the bible does not allow a definitive king list of the divided monarchy to be made.
6. The historical value or merit of Ptolemy's Canon
Please re-read AlanF's comments to you about this subject here: http://www.jehovahs-witness.com/10/86231/1432161/post.ashx#1432161 and some of his other comments and try to understand. It really isn't that difficult.
7. A Absolute Date for securing pivotal dates for the Old Testament
I've already mentioned one above which is 651 BC. Vat 4956 gives 568 BC as Nebuchadnezzar's 37th year, another absolute date. Let's take another astronomical text, LBAT 1420, which reports lunar eclipses for almost every year from the first of Nebuchadnezzar (604/603BC) to his 29th year (576/575BC). Here are a list of eclipse observations from this tablet and their absolute dates:
Oct 27/28 603 BC Nebuchadnezzar year 2
Apr 10/11 601 BC Nebuchadnezzar year 4
Feb 19/20 599 BC Nebuchadnezzar year 5
May 23/24 594 BC Nebuchadnezzar year 11
Apr 01/02 592 BC Nebuchadnezzar year 12
Mar 22 591 BC Nebuchadnezzar year 13
Jan 19 588 BC Nebuchadnezzar year 16
Jan 08 587 BC Nebuchadnezzar year 17
Aug 14/15 580 BC Nebuchadnezzar year 25
Feb 08 579 BC Nebuchadnezzar year 25
Jun 14 577 BC Nebuchadnezzar year 28
Dec 08 577 BC Nebuchadnezzar year 28
Jun 03 576 BC Nebuchadnezzar year 29
How many do you want?
