שמות, פרק ח׳, פסוק ו׳

The dialogue between Moses and Pharaoh reaches a critical turning point as they negotiate an exact time to end the plague of frogs. Pharaoh's response to Moses presents a psychological and logical puzzle. It is highly unusual that a ruler suffering from such a severe plague would choose to delay his own relief rather than demand an immediate end to it.

The primary approach among commentators is that Pharaoh asked Moses to pray immediately, but requested that the frogs actually depart the following day. Conversely, some suggest Pharaoh was not timing the end of the plague at all. Instead, he was setting the time for his own compliance, promising to let the Israelites go the next day [ריב״א, חזקוני, הטור הארוך].

To explain why Pharaoh would willingly suffer another day, three main perspectives emerge. The most prominent approach views Pharaoh's choice as a calculated test. Steeped in the beliefs of magic and astrology, Pharaoh suspected the plague was simply a natural phenomenon or tied to the alignment of the stars, which happened to be reaching its natural end. He assumed Moses knew this and was trying to take credit by expecting Pharaoh to ask for immediate relief. To expose what he believed to be a trick, Pharaoh chose to suffer an extra day. He knew that the powers of magic and demons are restricted to specific times and cannot be scheduled for a later date. By waiting for the current celestial influence to pass, Pharaoh intended to call Moses' bluff. When Moses agreed to the delay, it proved his power did not stem from sorcery [רב שמואל בן חפני, אבן עזרא, שפתי חכמים, אור החיים, מלבי״ם, ברטנורא, חתם סופר].

A different perspective suggests a misunderstanding. Pharaoh assumed Moses needed a significant amount of time to reverse the plague, so he tried to pressure him by setting a very tight deadline of just one day [רמב״ן]. However, others reject this, noting that if Pharaoh truly wanted to pressure Moses, he would have demanded an immediate end to the frogs [שד״ל]. A third approach interprets Pharaoh's answer as pure defiance and mockery. In this view, Pharaoh was challenging Moses, giving him until the next day while fully expecting him to fail [בכור שור]. Alternatively, it was an expression of doubt, as if to say he wished relief would come the next day but severely doubted Moses was capable of delivering it [הטור הארוך].

Moses agrees to follow Pharaoh's exact terms, confirming that the frogs will merely depart from him rather than being completely wiped out from the world [ספורנו]. Moses explains that the purpose of this precise timing is to prove that there is no power like God. While the upper forces of nature and the stars are limited and bound by fixed rules, God maintains absolute control over nature and can alter it at any moment He desires. The ability to schedule the exact hour of relief for the following day, answering a prayer conditioned on the future, serves as absolute proof. It demonstrates that God is the sole force behind both the plague and its removal, and that no other power in the world can compare to Him [רלב״ג, ספורנו, רש ר הירש, ביאור יש״ר, העמק דבר, אור החיים].
