The JW Scholar is guilty of scholastic dishonesty, or is just parroting the Society's dishonesty in the Appendix of the Let Your Kingdom Come book.
I think my previous post on Jeremiah and the Society's own statement stands on it's own. However, it really grinds me when people say that Josephus advocated 70 years of desolation.
The Society uses this quote from Josephus:
“Furthermore, Josephus elsewhere describes the destruction of Jerusalem by the Babylonians and then says that "all Judea and Jerusalem, and the temple, continued to be a desert for seventy years." (Antiquities of the Jews X, ix, 7) Hepointedly states that ‘our city was desolate during the interval of seventy years, until the days of Cyrus.’” (Against Apion I, 19) – Let Your Kingdom Come, 1981, italics the Society’s
Reading this paragraph seems to prove the 70 years of desolation. However, the Society italicized the word “desolate”. This distracts from the word “during” used by Cyrus. This is critical because the statement of Josephus does not directly prove that the city and temple were destroyed 70 years before the Jews release by Cyrus. It merely says these things happened during a 70 year period.
Just semantics?
Conspicuously absent from the Society’s examination is the following; in the same writing of Josephus, a few paragraphs later, he specifically addresses the temple in Jerusalem:
“These accounts agree with the true history in our books [the Hebrew Scriptures]; for in them it is written that Nebuchadnezzar, in the nineteenth year of his reign, laid our temple desolate, and so it lay in that state for fifty years ; but that in the second year of the reign of Cyrus, its foundations were laid and it was finished again in the second year of Darius.” - Against Apion I, 21
So, 70 - 50 = 20. There's your 20 year discrepancy. Josephus, the Bible, and secular chronology are all in agreement.
