Leo, you need to go back and read. As usual you are wrong in your interpretation. Tyre being rebuilt was brought up by 587 proponents to try to prove that the 40 year desolation of Egypt was wrongly interpreted just like Tyre being rebuilt prophecy. Tyre being rebuilt or not has nothing to do with the 70 year prophecy on Tyre in Isaiah. So you are wrong about who brought up Tyre being rebuilt but why not. You are wrong on most everything else as well.
In your very first post in this thread (#12), you mentioned Nebuchadnezzar's siege of Tyre and how the 40 years of Egypt was connected to it by discussing Ezekiel 29. You used that as a chronological basis to start the 40 years AFTER the siege of Tyre even tho the original oracle that mentioned the 40 years does not assume such a delay (and as I pointed out, the revised oracle does NOT mention the 40 years). Then in #24, you mention the "70 years of Tyre". That's the second reference to Tyre in this thread. In response to these references to Tyre that you brought up, stevenyc pointed out that Ezekiel's prophecy also claimed that Tyre would not be rebuilt and rassilion also pointed out that it bears on your reasoning about the chronology: "Fact: The prophecy about Tyre did not get fufilled during this time period. In fact the Insight book indicates it did not until several hundred years later. WHY then do you claim that this 40 years for Egypt must be fufilled during this time period. AND no there is nothing in EZEKIEL which makes it a necessity." Note that he recognizes, as I pointed out, that the oracle that mentions Nebuchadnezzar is not the one that mentions the 40 years and the oracle about the 40 years does not put it in the timeframe of Nebuchadnezzar. And note that his discussion about the Tyre prophecy pertains to your chronological arguments. And the discussion continued from there.
