Moses stands before the Egyptian king, agreeing to intercede and end the devastating plague of wild beasts, but not without laying down a firm boundary. The negotiation between the prophet and the monarch reaches a critical moment of tension, balancing diplomacy, divine timing, and a sharp demand for honesty.
Committing to pray to God, Moses sets the removal of the beasts for the exact time of the following day. There are several reasons for this specific delay. Some explain that Moses wanted to follow the pattern established during the plague of frogs, where the king himself requested the relief to come the next day [רמב״ן, הטור הארוך]. Others view this precise scheduling as a theological statement. By naming the exact time, Moses proved that the relief was a direct miracle from God rather than a natural occurrence. This prevented the king from assuming Moses was merely an astrologer who knew the natural hour the animals would retreat [רבנו בחיי, ביאור יש״ר]. From a practical standpoint, the timing simply reflected the logistics of the plague: just as it took the wild animals a full day to travel from the forests into the Egyptian cities, it would take them a full day to make the journey back [מלבי״ם]. Furthermore, the departure of the beasts differed significantly from the earlier plague of frogs. While the frogs died where they were, the wild beasts were sent back to their natural habitats so the Egyptians could not harvest and benefit from their valuable hides [רמב״ן, הטור הארוך].
As Moses agrees to the terms, he issues a severe warning, demanding that the king not act deceitfully again. The concept of deceit used here conveys a very specific type of betrayal: building something up high only to intentionally tear it down. It describes the cruelty of planting great hopes and making grand promises, only to immediately shatter that trust [רש״ר הירש]. Moses is directly cautioning the king not to repeat his previous behavior from the plague of frogs, where he promised to free the Israelites but then completely reversed his decision [אבן עזרא, מלבי״ם, ביאור שטיינזלץ].
In delivering this sharp rebuke, Moses employs a fascinating rhetorical strategy. He begins speaking directly to the king but suddenly shifts to referring to him in the third person. This subtle shift serves to maintain the dignity of the crown, slightly softening the severe warning while still giving the message profound weight. Additionally, Moses deliberately mirrors the exact phrasing the king had used earlier, signaling that while he is negotiating, he is not entirely bowing in submission [ברכת אשר על התורה, קאסוטו].
Calling a ruling monarch a deceiver is a bold move, seemingly violating the duty to show respect to royalty. However, this was a calculated debate tactic. The king had previously presented a strong logical argument, questioning why the Israelites needed to travel three full days into the desert rather than worshipping nearby. Lacking a definitive counterargument, Moses intentionally hurled an insult to provoke the king. The goal was to make the monarch angry and fearful, causing him to completely forget his logical point. The strategy proved successful; the king dropped the argument about the distance and later shifted to asking exactly who would be leaving [תולדות יצחק]. Despite this bold maneuver, Moses was willing to temporarily accept the king's compromise of not traveling too far. His primary focus was simply to achieve some forward momentum and secure the immediate release of the people, even if it did not immediately fulfill their ultimate goal [העמק דבר].
