Scholar, what do you have to say about Daniel 9:2 and the verses in Zechariah 1 and 7? Are these the same 70 years? Does the WBTS believe them to be?
These seventy years are in the time of Darius, as can be seen at the beginning of each chapter. He began ruling about 522 BC. By the time of the 4th year of Darius, it has already been some 20 years since the Jews returned to Jerusalem. When it talks about things like fasting for the past 70 years, what is this referring to? If not 607 BC, then when did these 70 years start?
And no, the WBTS has not given a good reasoning for 607 and the evidence is far from strong. The provide NO secular evidence. They merely pick a date (arrived at from secular sources), ignore another one, and count backwards. All they say is that it ends when the Jews return to Jerusalem in 537, ignoring Jeremiah 25:12 that says the 70 years is already completed before the king of Babylon is punished in 539. And they arrive at 607. But what is that 70 year period? That is up for debate. To apply it from the time of Jerusalem being destroyed at the end of Zedekiah's reign until the Jews return is clearly one interpretation, not hard evidence. It's only one theory and one that falls apart at that.
If the WBTS has provided evidence, please show us what it is. None of their stuff I've read goes beyond their "interpretation" - no real support or responses to questions of their interpretation.
Scholar, the way you dodge giving sources or restating "proofs" makes me wonder whether you're not just pranking us. Do you, in fact, know that there is no support for 607 and you're just here to annoy us? Is this some form of sarcasm to support 607 and say it is so well supported?
