Okay. First of all, the Bible's NB chronology does not work with the secular chronology. The Bible's and Josephus' chronology begins the 70 years of Jeremiah with the last deportation in year 23 of Nebuchadnezzar II and ends it in the 1st of Cyrus. Thus you have a period of 74 years from year 19 to the 1st of Cyrus. The Bible in Zechariah 1 establishes that 70 years after the fall of Jerusalem ends in the 2nd year of Darius. Zechariah 7 confirms that 70 years of mourning over Gedaliah ends in the 4th year of Darius. This at least establishes that Gedaliah died the year following the fall of Jerusalem, thus in year 20, and began to be mourned the following year, which was year 21 of Nebuchadnezzar II. The remnant of Jews then fled down to Egypt. Jehovah instructed them by Jeremiah to return to Judea, which they refused, after which Jehovah said he would send Nebuchadnezzar to kill them and only a few "escaped ones" would return to Judea after that. (Jeremiah 44:14,28)
Josephus records this last campaign by Nebuchadnezzar II as occurring in year 23 of Nebuchadnezzar which included the entire region of the land of Israel at which time he deported the Jews in Egypt into Babylon, obviously treking through Judea to fulfill Jeremiah 44:14, 28. According to 2 Chronicles 36:20 and Josephus in Antiquities 11.1.1, it was these last poor ones who had run down to Egypt and "escaped from the sword" who made up those of the last deportation (Jer. 52:30) who would serve Nebuchadnezzar II and "his sons" for a period of 70 years, ending the 1st of Cyrus.
Thus per both the Bible and Josephus, there is a 74-year gap from the fall of Jerusalem down to the 1st of Cyrus, and a 72-year gap from the mourning over Gedalliah in the seventh month and the 1st of Cyrus.
So now getting back to Zechariah 7, it is a legitimate question to ask WHICH "DARIUS" IS THIS? DARIUS THE MEDE OR DARIUS I (THE GREAT)?
If we follow the Bible, this would be a reference to DARIUS THE MEDE, because the Jews would have still been in exile 72 years after the fall of Jerusalem, which falls in year 4 of "Darius," meaning two things: 1) The Jews were still in exile and would be for another 2 years, and 2) Darius the Mede was the grandson of Nebuchadnezzar II.
Our confirmation that the Jews were still in exile in the 4th year of Darius is found in verse 7 where it says: "Should you not obey the words that Jehovah called out by means of the former prophets, while Jersalem happened to be inhabited...?" So Jerusalem was not inhabited in year 4 of this Darius, thus confirming the Jews were still in exile, thus confirming this is a reference to Darius the Mede and not Darius the Great.
This means the WTS, COJ and so many others trying to link these references to 70 years after the fall of Jerusalem ending in year 2 and 70 years after the mourning for Gedaliah in month seven in year 4 of Darius the Great is both erroneous and inapplicable. This leads us to a new reality and critical truth regarding the Bible's chronology of the NB Period and that of popular secular history which date the fall of Babylon in 539 BCE and the return of the Jews in 537 BCE, both of which secular and the WTS prescribe to, and that is this: The Bible's and Josephus' NB Period is 26 years longer than that of secular history. The two chronologies are completely incompatible.
Does this mean the Babylonians recorded the wrong history? No, not at all. They recorded the correct history. But the records that survive for this period did not come from the Neo-Babylonian Period, but from the Persian Period, during the reign of Darius II. We know this for a fact because the Babylonian Chronicle clearly states it was "copied" in the 22nd year of Darius II (I know, yet another "Darius"!). The presumption, therefore, at this point (or maybe it's a confirmation) is that the Persians revised the Babylonian records, removing 26 years from the Babylonian kings in an effort to expand the reign of one or more of the Persian kings.
This is apparent from Ezra 6:14,15 where the Bible limits the rule of Darius I to six years. Darius I died in his sixth year, the year the temple was completed. Secular history, which comes from the Greek historians, claims Darius I ruled for some 36 years. So you have another direct contradiction between the Bible and secular history. A big mess. But there's no way out of it.
The WTS and COJ and others, as some here, try to somehow harmonize the revised secular history with that of the Bible using various theories, but it never works as we can see from the discussion here. But it does work when you use the Josephus timeline, which agrees with the Bible's chronology, where the 70 years begin with the last deportation in year 23 of Nebuchadnezzar. Again, this would confirm four things not recognized by false chronologists like the WTS and those trying to authenticate the Persian-revised NB records which Persians also paid to influenced Greek historians to revise and harmonize their history with the revised Persian history:
1) The Jews were still in exile during the reign of Darius the Mede.
2) Dairus the Mede ruled for a full 6 years before the 1st of Cyrus.
3) Darius the Mede and Cyrus were never co-rulers over Babylon.
4) Darius the Mede was the grandson of Nebuchadnezzar II.
SUMMARY: There is no way to harmonize many scriptures in the Bible with the current NB timeline which is 26 years shorter than the Bible's timeline, as well as 26 years shorter than Josephus' timeline, both of which begin the 70 years of Jeremiah in year 23 of Nebuchadnezzar II. There is no mystery when either the Bible or traditional Jewish history begin the 70 years of Jeremiah. It is apparent, though, that this is an attempt to establish that premise since historians discussing the 70 years seldom mention Josephus or twist Zechariah 7 into applying to Darius I rather than Dariius the Mede. When you follow the Bible or Josephus, you have perfect harmony with Zech 7 which shows the Jews still in exile and Jerusalem still desolated in year 4 of Darius the Mede, some 72 years after the fall of Jerusalem. This has absolutely nothing to do with whether Babylon's domination over the first nation it conquered just happened to be close to 70 years based on the revised chronology. In fact, Babylon's revised chronology could work out to be exactly 70 years over the nations. It would not affect the Biblical reference that those last deported out of Egypt must serve Nebuchadnezzar and his sons for 70 years, one of those sons being none other than Darius the Mede who ruled for a full six years before Cyrus became the official king over all of Persia, including Babylon, beginning his rulership with year 1 at that time, and releasing many peoples back to the homeland, including the Jews.
Nice discussion. But you need to include ALL the chronology theories not just two erroneous ones to find harmony. The relative chronology of the Bible and Josephus is 26 years longer than the popular secular history. You can ignoe this factor if you want, but it will not change. At this point, revisionism by the Jews or the pagans or both is inevitable.
Cheers.
