John Wesley on Isaiah 23:15

Forgotten - Neglected and forsaken. Seventy years - During the time of the Jewish captivity in Babylon. Tyre was taken by Nebuchadnezzar, Jer 27:3,8 Ezek 26:7, a little after the taking of Jerusalem and was restored by the favour of the Persian monarchs after the return of the Jews. One king - One royal race of Nebuchadnezzar, including his son, and his son's son, in whom his family and kingdom were to expire. Sing - She shall by degrees return to her former traffick, whereby she shall easily entice the merchants of the world to trade with her, as harlots use to entice men by lascivious songs.
