The recognition of God's absolute control over the laws of nature stands at the center of historical revelation. The great miracles of the Exodus are not merely isolated events from the past. Instead, they serve as a continuous testimony that shapes human awareness across generations, firmly establishing Divine providence in the world.
The primary approach among commentators is that the memory of these historic signs and wonders remains famous and widely discussed by everyone up to the present. Taking a broader view, [מלבי״ם] suggests that supernatural guidance and miracles, which break the natural order, have actually never ceased in any generation. On the other hand, [חומת אנך] offers a more physical interpretation, explaining that the physical impact of the plagues remains visible in the land of Egypt. For instance, tradition notes that locusts never cross into Egypt's borders, and hail never falls there, serving as living proof of those historical events.
These wonders impacted both the Israelites and the rest of humanity, particularly the Egyptians. The miracles performed among the other nations were executed specifically for the sake of the Israelites [רד״ק] and in their merit [צאינה וראינה]. A prominent approach notes that these events operated on both nations at the exact same time, but with opposite effects. God performed miracles that brought good to the Israelites and harm to the Egyptians simultaneously. A clear example occurred at the splitting of the sea, where the very same cloud provided light for the Israelites while casting darkness upon the Egyptians [רש״י, מצודת דוד, רד״ק]. Furthermore, the plagues completely bypassed the area where the Israelites lived. Alternatively, [חומת אנך] suggests that the plagues struck the Israelites for a brief moment just so they could experience and understand their nature, before immediately moving on to strike the Egyptians.
Ultimately, through these profound wonders, God established a praiseworthy reputation for Himself that remains clear and evident today [מצודת דוד, ביאור שטיינזלץ]. This widespread fame forces humanity to recognize Him [רד״ק]. It proves to the entire world that God is the ultimate Creator and Overseer, possessing the power, wisdom, and will to overturn the laws of nature whenever He chooses [מלבי״ם].
