Adam Clarke on Isaiah 23:17

After the end of seventy years - Tyre, after its destruction by Nebuchadnezzar, recovered, as it is here foretold, its ancient trade, wealth, and grandeur; as it did likewise after a second destruction by Alexander. It became Christian early with the rest of the neighboring countries. St. Paul himself found many Christians there, Act 21:4. It suffered much in the Diocletian persecution. It was an archbishopric under the patriarchate of Jerusalem, with fourteen bishoprics under its jurisdiction. It continued Christian till it was taken by the Saracens in 639; was recovered by the Christians in 1124; but in 1280 was conquered by the Mamelukes, and afterwards taken from them by the Turks in 1517. Since that time it has sunk into utter decay; is now a mere ruin, a bare rock, "a place to spread nets upon," as the Prophet Ezekiel foretold it should be, Eze 26:14. See Sandy's Travels; Vitringa on the place; Bp. Newton on the Prophecies, Dissert. xi.
