I have spent many hours pouring over the chronology.....I too come up with the same conclusions as you. The elder I was talking too would not know...The first elders who met with me several months ago where stumped when I showed them this, they marked down all the scriptures I showed them and then never mentioned it again...I then showed them that according to WT chronology Daniel would have been somewhere around 95 in the third year of Cyrus rule 535..the last mention of him and also that the Jews who had returned and were rebuilding the temple in 518 would have been between 95 and 100 if the temple was destroyed in 607 when over 500years prior to this David had said mans lifespan was 70-80 years. Did it seem reasonable that captivity would lengthen instead of shorten your life.
If scholar and the WTBTS are correct it means there has been a concerted effort by Egyptians, Babylonians, Assyrians and the Jewish nation for 2600 years to conceal and hide the evidence needed to support the WT claims.
I do know that Jesus had the book of Daniel and he never mentioned using chronology to mark his return. The apostles had the Holy spirit even bringing ones back from the dead, they never mentioned using chronology to pinpoint his return.
Does it seem reasonable that such an accurate time indicator would be in the bible, why would Jesus give his main adversary the Devil the needed info to pinpoint his return. Maybe the angels have no comprehension of human language...hardly they spoke with many faithful ones throughout the scriptures.
Why did Satan wait until after he was thrown out of heaven to create such a stir. If you knew someone stronger than you was coming and basically going to throw you out of your apartment would you create more havoc with all his belongings before or after he arrives...or did Satan because he's read the scriptures and he's so submissive wait until the appointed times of the nations had been fulfilled before starting to take vengence on the earth.
Why did Jesus on his way to Jerusalem the very last time tell the Apostles that they were going there so that all the remaining phrophecies concerning the Messiah might be fulfilled. This would include Daniels and all the other prophets before Christ. The only ones left were the ones he said concerning the last days of the Jewish system of things which he fulfilled right down to the letter up to 70CE when that system was destroyed during a great tribulation which as Jesus stated had not occurred before , No nor would occur again. What does No nor will occur again mean...maybe sometime again or except in its second fulfillment which the spirit filled apostles knew nothing about but an earnest businessman and a lawyer would piece together 2000 years later with the help of the bible and the pyramids. Its no wonder the Finished Mystery stated C.T Russell had a headache everyday for twenty years...I've had one everyday for 6 months reading his thoughts on paper.
Scholar can you provide the names for the missing 20 years in babylonian chronology to support the 607 date. You said you have 30 years invested in this research...share your finds with us...just the names and dates of the rulers and where this info can be found. I am truly open to dig back into my research if needed, the reason I started digging originally was to bolster my beliefs not fuel my doubts into a raging forest fire.
