Pharaoh’s advisers tried hard to explain away all the plagues.

Even when the Red Sea split, allowed the Jews free passage, and drowned their enemies, there were those who ascribed the entire event to natural causes.

Such is human nature, to reflexively seek out a natural explanation for every event.

But a Jew, quite the opposite, ponders a natural occurrence and sees a miracle.

Because a Jew has an innate inner conviction that there is nothing else but G‑d. There is no nature—it is all by His hand.
