scholar:
According to you but most scholars prefer 586 rather than 587 so you have a BIG POBLEM here
It is not the case that a significant majority of scholars prefer 586, but any who do are wrong. No "poblem" for me whatsoever. Even mother Watch Tower disagrees with you.
The Watchtower, 1 October 2011, page 31:
Secular historians usually say that Jerusalem was destroyed in 587 B.C.E.
The Watchtower, 1 November 2011, pages 22, 27:
However, most scholars date the destruction of Jerusalem at 587 B.C.E. ... At present, the majority of secular historians believe that Jerusalem was destroyed in 587 B.C.E.
My suggestion to you is to consult other translations more particular how this verse is rendered in the NWT-Reference which is more to the point.
𤣠Most translations of Jeremiah 29:10 properly refer to 70 years for Babylon. Even in the rendering of the few translations that incorrectly allude to 70 years as a period at Babylon, the 70 years doesn't include the journey home, and allows the 70 years to end before attention is given to their return. But the JW interpretation is a distorted mess because they say the 70 years (which supposedly started more than a decade after most of the Jews were already in exile) ended only once they'd arrived in Judea. Worse still, in the JW interpretation, most of the Jews are in exile for over 80 years, some are in exile for less than 70 years and others are in exile for about 65 years.
There is nothing new in any of your other recent responses. Just the same old nonsense based on JW wishful thinking.
