I enjoyed your series of videos attempting to refute the validity of 607 BCE for the Fall of Jerusalem. No doubt there are some technical errors in your topics but some of which have already been coorected by Jeffro. You have contributed nothing new to this long standing academic debate for all that you have presented is simply a rehash in a pictorial form of Carl Jonsson's Gentile Times Reconsidered. Your arguments against the interpetation of the seventy years as explained by the Witnesses fails on several grounds and have long been debated and refuted on this website over many years. Chronology is very complex and much of which is subject to interpretation and that is why that in many reference works there is single agreed tabulation of OT Chronology and this is especially manifest when it comes to the Divided Monarchy.
WT chronology as produced by celebrated WT scholars over many decades is superior to all others in that it alone is faithful to the biblical text, biblical theology, secular history, archaeology, historiography and hermeneutics. It particularly has the advantage of its simplicity and rooted in Prophecy. Scholars have and continue to stumble over an interpretation of the seventy years, they cannot agree as to its beginning and end nor its duration and this is where you have a major problem. Carl Jonsson who has researched this subject most thoroughly has not decided whether 605 or 609 BCE is the begiining of the seventy years for either date has the acceptance of some scholars. The seventy years has proven to be one of the most complex and highly disputative subjects in OT history and it is only the Witnesses that have solved the problem with a very simple methodology a prime requisite for any chronologist.
The ending of the seventy years at Babylon's Fall in 539BCE simply does not work because Jeremiah clearly shows that the seventy years was one of servitude, exile and desolation and these three factors could only conclude at the point of the Exilic Return in 537 BCE. Jeremiah is quite emphatic about the seventy years and it most certainly belonged to Judah and not Babylon as you maintain. The ending of the Exile in 537 BCE is the best candidate for this event according to current scholarship fore 538 BCE is considered to be impossible and 535 and other later dates are simply impossible. Most reference works such as Biblical history, atlasses and scholarly papers in journals tend to favour 537 over any other date.
However, one of your biggest problems is the fact that even to this day scholars do not know the precise calender year for the Fall whether it is 586 or 587 BCE for the Fall. The scholarly literature has always and continues to this day favour the 586 date as opposed to 587. So this means that any argument against a definite, calculated date such as 607 is superfluous if such critics cannot determine a precise calender date for the Fall. You would need to get this right before saying that 607 is wrong.
Your presentation lacks substance and suffers from a lack of careful exegesis, it amounts to eisegesis rather than exegesis and simply reflects a biased opinion. Throughout your entire preentation you omit any reference to Josephus who had a lot to say about the seventy years and ALL of his comments support WT Biblical chronology and not that of Neo-Babylonian chronology.
