I have read shlomo ishtov and moshe shulman's articles on the Jewish perspective of Daniel 9 but my question is more specific. According to these articles the prophecy of Jeremiah 29:10 is made at the time of the destruction of the first temple ca. 586 BCE. Is there any reference in the book of Jeremiah or elsewhere in the Tanach which provides evidence that this is the date rather than some date earlier during Zedekiah's reign? Thanks.
