I would love to get the author of http://thirdwitness.com on phone, Skype whatever.
There are so many things left out that MATTER!!
Just one little tiny example related to his point on 607 which will prevent you from getting past the first page.
Initially Russell who took the idea of applying Daniel's prophecy to calculating the beginning of Jesus' parousia from Barbour (spelling, Miller etc) initially said the Pyramid of Giza's dimensions calculated to 1874. NOT 1914 at least not yet.
Suddenly miraculously in 1903 Russell then had to produce "new light" because well obvious 1874 was buptkis so he inexplicably changed the dimensions so they added up to 1914.
So the author of this site left these key pieces out. We haven't gotten off his first page on the subject yet btw.
Originally in calculating the Gentile Times ( I won't bore you with the entire prophecy & calculations here) the original date wasn't even 607 BCE it was 606! Why well that's because they forgot about the zero year!
Before I forget we still haven't left his first page on the matter. Now how do JW's arrive at 606 errr I mean 607 well they simply add the 70 years of desolation to the date factually known and accepted by all of 539 when Babylon was sacked by Cyrus.
So we just add 70 years to 539 and we get 609 wait what???
This is where it starts to get interesting again. Now I won't go into it in detail but it was 500 miles or more depending on route to return to Jerusalem when Cyrus decreed in his first year of rule to let the exiles return (see Ezra).
It order for this to work the exiles MUST return in 537. This cannot be proven Again can't go into that detail but you should look into the commiseration year of Cyrus and Darius.
Pyramids, 606, Nudging Pyramid inches to go from 1874 to 1914, iffy 537 and we haven't really gotten off the first page.
