This signifies the complete disappearance of the ancient walled city at ground level. There is no record telling us Tyre had inner city walls other than its outer protective city wall. She will be a place for the spreading of nets in the midst of the sea, for I have spoken,' declares the Lord God, 'and she will become spoil for the nations. This passage does not mention when Tyre will become a fishing port. Fishermen normally spread their nets in their premises.
Places having fishing nets spread out indicate there is settlement of fishermen.
Therefore, the prophesy does not mean the land will be void of all life-forms. A fishing town or village does not equate a city, less do they equate a walled city. Building and settlement in the locality is not the same as building and settlement in the walled city. The nations could hardly be interested in a fishing port. Skeptics claim that Tyre was an island city, and do not incline to show archaeological evidence for a mainland Tyre.
