The Babylonian empire didn't start until Assyria was finally defeated in 612 BC. Then as we know Babylon supposedly destroyed Jerusalem in 607 according to WT. Before Jerusalem was destroyed Babylon had taken Jerusalem and taken prisoners including the king and deported them to Babylon and then according to Ezekiel at 33:21 twelve years into their captivity a man from Jerusalem came and told him the city had been destroyed.
Ok so how does Jerusalem get conquered 12 years before 607 when the Babylonians hadn't even become the major power yet??
According to cuneiform texts and the chronicles of Nebuchadnezzar Jerusalem was originally sacked by Babylon in 598. 598-12 years the Jews were in captivity when the man said the city had been destroyed equals 586. Doesn't a lot of historians believe this to be the date of Jerusalems destruction?
