שמות, פרק ט׳, פסוק י״ח

The plague of hail marks a dramatic turning point in the sequence of plagues, bringing an unprecedented climatic upheaval specifically tailored to the natural environment of Egypt. Rather than an event of sheer destruction, the hail served as a display of precise divine control, blending strict warning with a measure of mercy. An exact time was set for the plague to begin the following day to prove beyond any doubt that this was not a random natural occurrence [מזרחי, ברטנורא, קאסוטו]. To make this schedule absolutely clear, Moses scratched a mark on the wall and told Pharaoh that the hail would begin the very moment the sun reached that exact spot [רש״י, מלבי״ם]. Unlike the earlier plague of pestilence, where livestock were scattered across fields and the exact start of the disease was hard to observe, the hail required a tangible, undeniable starting point. Furthermore, setting a precise hour was an act of mercy from God. The primary goal of the hail was to destroy the crops, not to kill people or animals. By knowing the exact time, the Egyptians were given the opportunity to act quickly and bring their livestock indoors to safety [רמב״ן, בעלי ברית אברם, שפתי חכמים, גור אריה, העמק דבר].

The sheer wonder of the event was magnified by its setting. Egypt is a land that relies entirely on the Nile River rather than rainfall, and phenomena like heavy rain or hail are virtually non-existent there, with the land typically receiving only dew. The sudden downpour of hail completely shattered the laws of nature as the Egyptians knew them, triggering deep anxiety [רמב״ן, אבן עזרא, רש״ר הירש, הטור הארוך]. Adding to the terror, the hail itself was not a normal weather event, but a complex miracle consisting of fire and water mixed together [העמק דבר, משכיל לדוד].

Commentators differ regarding just how unprecedented this storm was on a global scale. One approach suggests that while similar hail might have fallen elsewhere in the world—such as the hailstones in the days of Joshua or the sulfur in Sodom—it had never been seen in the arid land of Egypt [רמב״ן, הטור הארוך]. Another perspective argues that a storm of this magnitude had never occurred anywhere in the world, making its appearance in Egypt all the more astonishing [רבנו בחיי, מלבי״ם, ביאור יש״ר].

The destruction was described as an event unseen since the very foundation and initial settlement of the nation [שטיינזלץ]. This historical reference holds special weight, as Egypt's constant flooding by the Nile meant the land required extensive engineering and unique infrastructure just to become habitable in the first place [שד״ל]. Interestingly, describing an unprecedented event by referencing the time since the land's founding was a common expression in ancient Egyptian administrative language, adding a layer of cultural resonance to the warning [קאסוטו].
