'scholar':
The attention given to the Exiles was their release from Exile by an official decree, returning home on time thus fulfilling the 70 years as prophesied and described in detail by the Chronicler.
Entirely invalid response (and there actually wasn't any special decree just for the Jews, Cyrus just had a general policy of allowing conquered people to follow their religious beliefs in order to quell civil unrest). Giving attention to their return before the end of the 70 years directly contradicts the direct statement at Jeremiah 29:10. But thanks for confirming once again that JWs don't really care what the Bible actually says when it disagrees with Watch Tower Society doctrine.
Just use your plain common sense and just read the text that is if you believe the text
It is not necessary to believe a text is true in order to assess what it says. However, the descriptions in Jeremiah of 70 years as a period during which the nations were subject to Babylon does nicely fit the period from the fall of Assyria in 609 BCE until the fall of Babylon in 539 BCE. And Jeremiah's further description of attention being given to the Jews' return after Babylon's 70 years also nicely fits the fact that some of the Jews returned to Jerusalem in 538 BCE after Persia began to reign and began work on the temple foundations in Cyrus' second year, 537 BCE.
or even the whole Bible for you have already discarded Daniel to the trash can.
Fallacy of composition.
