I'd really like an answer to this. Its probably been discussed already and if so, feel free to send the link.
As a dub, I always marvelled at this prophecy - how Jehovah was able to name the person who would overthrow Babylon and in what manner he would do it (drying up the river, gates unlocked, etc.) and so far in advance too. I loved the Isaiah and Daniel books and all the "deep" matters like prophecy and their fulfillment.
For a long time, I didn't want to know the truth about this prophecy and wanted to believe it was as I was taught. However, I feel ready for it now so hit me with it!
