תהלים, פרק קל״ה, פסוק ח׳

God's greatness extends far beyond the natural wonders of creation; it is powerfully revealed through His active, supernatural intervention in human history. The plague of the firstborn stands out as the ultimate display of this intervention. It was the final, decisive blow that broke Egypt's resistance and directly resulted in the Israelites' transition from slavery to freedom [רד״ק, מאירי, ביאור שטיינזלץ].

This specific event highlights God's exact and personal oversight of the world. Because God carried out this plague Himself rather than relying on a messenger, it proved His unique ability to identify with perfect precision exactly who was a firstborn [אלשיך, מצודת דוד]. The fact that this judgment applied to both humans and animals magnifies the scope of His awareness, showing that His providence reaches into every level of the physical world.

For a person of faith, God's power is already visible through the steady, daily laws of nature. Therefore, an open miracle that completely shatters the natural order serves a very different purpose. These supernatural wonders were performed specifically for Pharaoh and the Egyptians. Because they refused to acknowledge God through the quiet design of the natural world, they required overwhelming, unnatural signs to finally understand His absolute power and control [מלבי״ם].
