[Trying to justify the failed biblical prophecy of Tyre being destroyed]

But Isaiah had already prophesied (Is. 23:15) that Tyre would be rebuilt. Therefore, as John Gill comments, this should not be understood as if Tyre would never be completely rebuilt, but it should be understood as not rebuilt in the same grandeur and occupy the same position among the nations.
But there are more layers in this prophesy. Tyre was also destroyed by Alexander. And it was he who destroyed the city completely. And by founding Alexandria he changed the track of commerce forever.
