'scholar':
This is utter nonsense for the Bible clearly teaches that the 70 years was a period of Exile a period of servitude to Babylon under its domination and a Desolation of Judah beginning in 607 BCE and ending in 537 BCE.
Liar. The Bible never mentions 70 years of exile. That is why you always defer to these stupid 'summaries' of JW belief instead.
Further, your interpretation is bogus because you do not believe in these events for you do not believe the Bible so any opinion you express is insincere and inauthentic.
Fallacy of division.
You should be paying attention to the 42 months, seven woes and the seven trumpets
I've given them due attention. The '42 months' ended nearly 1,953 years ago, so it's not a cause for concern. Similarly, the events symbolised by the 'woes' and 'trumpets' relate to the period of early Christianity (representing a combination of various real and imagined events), and are no cause for concern, despite the claims of conspiracy theorists, crackpots and fear-mongerers.
