2. Tyre-- (Jos 19:29; 2Sa 24:7), literally, meaning "the rock-city," Zor; a name applying to the island Tyre, called New Tyre, rather than Old Tyre on the mainland. They were half a mile apart. "New Tyre," a century and a half before the fall of Jerusalem, had successfully resisted Shalmaneser of Assyria, for five years besieging it (MENANDER, from the Tyrian archives, quoted by JOSEPHUS, Antiquities, 9.14. 2). It was the stronger and more important of the two cities, and is the one chiefly, though not exclusively, here meant. Tyre was originally a colony of Zidon. Nebuchadnezzar's siege of it lasted thirteen years (Eze 29:18; Isa 23:1-18). Though no profane author mentions his having succeeded in the siege, JEROME states he read the fact in Assyrian histories.
      Aha!--exultation over a fallen rival (Ps 35:21, 25).
      she . . . that was the gates--that is, the single gate composed of two folding doors. Hence the verb is singular. "Gates" were the place of resort for traffic and public business: so here it expresses a mart of commerce frequented by merchants. Tyre regards Jerusalem not as an open enemy, for her territory being the narrow, long strip of land north of Philistia, between Mount Lebanon and the sea, her interest was to cultivate friendly relations with the Jews, on whom she was dependent for corn (Eze 27:17; 1Ki 5:9; Ac 12:20). But Jerusalem had intercepted some of the inland traffic which she wished to monopolize to herself; so, in her intensely selfish worldly-mindedness, she exulted heartlessly over the fall of Jerusalem as her own gain. Hence she incurred the wrath of God as pre-eminently the world's representative in its ambition, selfishness, and pride, in defiance of the will of God (Isa 23:9).
      she is turned unto me--that is, the mart of corn, wine, oil, balsam, &c., which she once was, is transferred to me. The caravans from Palmyra, Petra, and the East will no longer be intercepted by the market ("the gates") of Jerusalem, but will come to me.
