SCHOLAR. This is not true!!
You need to read all of the Josephus' references to the seventy years of which there are several for these show quite clearly that the seventy years in the opinion of Josephus ran from the Fall until the Return. Further, this period was of exile, servitude and desolation of the land, city and temple. These collective references nicely support the understanding of the seventy years according to the Bible and published by the 'celebrated WT scholars.
It does not run from the "fall" of Jerusalem, but the last deportation. Josephus describes specifically a last compaign into the region where the Jews were deported from Egypt in year 23. It is at that point that the 70 years begins in connection with when the people were "removed out of their land."
So you need to correct your statement here as far as when Josephus is claiming the 70 years begins. It is with the last deportation.
On that note, where do you think the Jews came from for the last deportation in year 23 of Nebuchadnezzar? There were still Jews in the land up to year 23. The Bible clearly says in Jer. 44:14,28 that those who were left "remaining from the sword" from Egypt would return to Judea. Oh, sorry, let me quote those scriptures for you:
14 And there will come to be no escapee or survivor for the remnant of Judah who are entering in to reside there as aliens, in the land of Egypt, even to return to the land of Judah to which they are lifting up their soul[ful desire] to return in order to dwell; for they will not return, except some escaped ones.’”
28 And as for the ones escaping from the sword, they will return from the land of Egypt to the land of Judah, few in number; and all those of the remnant of Judah, who are coming into the land of Egypt to reside there as aliens, will certainly know whose word comes true, that from me or that from them.”’”
Now stop thinking about yourself for just one second and think about ME! I have to try and harmonize this with everything. WHEN did these people actually return to Judea? Did God also have Nebuchadnezzar kill Jeremiah and Baruch? We know better!
Now the easy explanation, factoring Josephus' account that the last deportation was in year 23 of Nebuchadnezzar from Egypt is that those of the last deportation did include Jeremiah and Baruch and on their way to Babylon that very year they did trek through Judea again, meaning the land was not desolated until after that final deportation. This is the reference by Josephus for the seventy years, when the people were "removed out of their land" not the fall of Jerusalem!
Let's again consider Ant. 11.1.1 with my highlights...
IN the first year of the reign of Cyrus which was the seventieth from the day that our people were removed out of their own land [not the fall of Jerusalem] into Babylon, God commiserated the captivity and calamity of these poor people, according as he had foretold to them by Jeremiah the prophet, before the destruction of the city, that after they had served Nebuchadnezzar and his posterity, and after they had undergone that servitude seventy years, he would restore them again to the land of their fathers, and they should build their temple, and enjoy their ancient prosperity.
Note that the context of this reference is not to the fall of Jerusalem but when they were "removed out of their own land." This is just a reference to the final deportation which was from Judea since those who were rescued from Egypt did indeed return to Judea. That proves the land was not desolated completely until the last deportation, year 23.
So, Scholar, you can't keep saying these 70 years are from the "fall" of Jerusalem and include Josephus in that reference. Josephus is not dating the 70 years from the fall, but from the last deportation from Egypt.
If this is not your understanding or you think this does not contradict your position, could you please explain how I'm getting this detail wrong? Thanks. Otherwise, it just looks like you're uninformed about Josephus' reference to the 70 years.
