Ezekiel 26:6

And her daughters - The places dependent on Tyre. As there were two places called Tyre, one on the main land, and the other on a rock in the sea, opposite to that on the main land, sometimes the one seems to be spoken of, and sometimes the other. That on the land, Palaetyre, was soon taken; but that in the sea cost Nebuchadnezzar thirteen years of siege and blockade. The two formed only one city, and one state.
