The answer is: Plague of Darkness|Darkness

Exodus 10:21 - Like the third and sixth plagues, this plague was unannounced to Pharaoh. The darkness was an insult to the Egyptian sun-god Ra (or Re).

The ninth plague incorporated not just a physical manifestation but a deeper symbolic act against an entire belief system intertwined with Egyptian idolatry. This profound darkness spanned across Egypt for three days but curiously didn't affect the Israelites living in Goshen. Imagine being enveloped in utter blackness where you cannot see your hand in front of your face—a state so devastating it compelled isolation and reflected a spiritual desolation.

Ra, the Egyptian god of the sun, was a source of life and warmth, intimately connected to their agricultural cycles and daily routines. By confronting Ra through this supernatural darkness, a compelling invitation was extended to challenge long-held notions of power and control. It highlights the tenacity of Egypt’s faith in their deities, even as calamity befell them, raising profound questions about faith, power, and authority in one’s own life.

If we dive deeper, we discover that darkness isn't just physical; it's often perceived as metaphorical. For instance, in various biblical texts, “darkness” can symbolize confusion, suffering, and the absence of truth. Eerily enough, this reconsideration proves relevant even today as we confront personal "dark times." This plague also echoes in literature and culture, suggesting darkness can create the space for reflection, revelation, and ultimately, change. Not just an act of dominance, but perhaps an invitation to see the world with new eyes—and to recognize the light that exists even amid profound darkness.
