Summary
Ezekiel’s prophecy that Tyre would be destroyed by Nebuchadnezzar was not fulfilled in the manner predicted by the prophet. This is demonstrated from extra-biblical literature, supported by archaeological evidence, and acknowledged by Ezekiel himself in a later prophecy. As a result, it is argued that the passage supports a world-view in which God is sometimes willing to adjust his plan from what he initially declared. This supports a relational view over the conventional deterministic view of divine foreknowledge, and it helps ease the tension between the test of a true prophet and a true prophet whose prediction is not fully realised.
