I apologize if a thread for this has been created already. I found the following in the Awake May 2013, Page 13
Earlier, in 607 B.C.E., Babylonian armies razed Jerusalem
and led most of the survivors into exile. How long
would the Jews be held? God said: “When seventy years
have been fulfilled I shall call to account against the king
of Babylon and against that nation . . . and I will make it
desolate wastes to time indefinite.”—Jeremiah 25:12.
As mentioned, Cyrus captured Babylon in 539 B.C.E.
Soon thereafter, he released the Jews, who began to arrive
in their homeland in 537 B.C.E.—exactly 70 years after
their deportation. (Ezra 1:1-4) As for Babylon, it eventually
became “desolate wastes”—again confirming the
accuracy of Bible prophecy.
The writer contradicts himself within two paragraphs. Is it 70 years for Babylon (fulfillment in 539 BCE) or is it 70 years of exile (fulfillment in 537 BCE)
The writer could have used the more questionable WT translation of Jer 29:10, but he decided to use the "wrong" verse instead (Jer 25:12).
WHY???
Jeremiah 29:10 For this is what Jehovah has said, ‘In accord with the fulfilling of seventy years at Babylon I shall turn my attention to ? YOU ? people, and I will establish toward ? YOU ? my good word in bringing ? YOU ? back to this place.’
