The answer is: Buttocks

Isaiah 20:2-4 - Isaiah walked naked and barefoot for three years as a sign against Egypt and Cush, symbolizing their impending shame and captivity.

Isaiah’s actions might raise a few eyebrows today. Walking around nude, even with a deep spiritual message behind it, indicates just how far prophets pushed the envelope to grab attention! His nakedness symbolizes more than just physical exposure; it signifies the disgrace Bethlehem would face at the hands of conquerors.

The time much be noted—three-years of this spectacle was no frivolous performance. Isaiah was tapping into a rich tradition of prophetic acts that caught the eye of onlookers while delivering a powerful message. Similar provocations appear in the stories of other prophets like Jeremiah, who once broke a clay jar echoing themes of destruction and humility.

Interestingly, the imagery of nakedness goes beyond this quirky story. Numbers 32:23 advises that your sins will find you out—what a unique juxtaposition! The contrast between shame and vulnerability is a prevailing theme throughout the Bible, seen again in Adam and Eve's realization of their nakedness in Genesis.

Symbolism aside, these prophets reminded the people the importance of understanding their decisions lead to consequences, often with a satirical twist. The connection between body and message resonates; it's as if God's painting vivid, zany illustrations for eyes to see. So while this moment seems bizarre, it embarks a profound look at human nature, humility, and accountability that reverberates through Scripture.
