The prophecy in Isaiah 17 concerning the destruction of Damascus is unique amongst Isaiah's oracles against foreign nations because:

A It is the only oracle delivered solely to the nation of Syria, without mentioning Israel. B It is unusually detailed in its description of the economic collapse that would precede the city's fall. C It predicts Damascus will cease to be a city, becoming a ruinous heap, a fate not explicitly stated for other cities. D It specifically names the Babylonian king who would carry out the destruction, providing a precise timeline.
