במדבר, פרק כ׳, פסוק י״ח

The Israelites' request to pass through the land of Edom on their journey to Canaan was met with a harsh and absolute rejection. This refusal did not come solely from the leadership. Instead, the entire nation of Edom agreed with one voice to deny them entry [הטור הארוך]. The Israelites initially asked to travel directly through the populated cities and the very heart of the country [ריב"א, מלבי"ם, בכור שור]. Their intention was peaceful and mutually beneficial. They hoped to use the main highway, pay tolls, and contribute to the local economy [חזקוני].

However, the people of Edom deeply distrusted the promise that no harm would be done [בכור שור, אדרת אליהו]. They suspected the Israelites were plotting to conquer their cities through deception [חזקוני]. Furthermore, they viewed the prospect of an entire nation marching through their territory with flags and signs of authority as a profound violation, feeling as though the Israelites were marching through their very body and heart [פענח רזא, שפתי כהן]. Beyond the immediate perceived insult, Edom's refusal was driven by strategic and psychological fears. They worried that even if the passage was peaceful, the Israelites would learn the layout of the land and use this intelligence for future wars [ברכת אשר על התורה]. The leadership also feared that merely watching the Israelites pass by would provoke their own aggressive urges to attack them [שפתי כהן].

Understanding this deep sensitivity, the Israelites eventually modified their request, asking only to use the outer bypass roads away from the cities. Edom still refused, though their second rejection was no longer based on the fear of their inner borders being penetrated, but simply a strict denial of entry [ריב"א, פענח רזא, מלבי"ם].

Edom's rejection was accompanied by a severe threat to confront the Israelites with the sword. The primary approach among commentators is that this specific threat represents a clash of historical blessings. Edom was essentially declaring that while the Israelites arrived relying on the power of prayer, trusting that God would hear their cries as He did for their ancestors, Edom would meet them with the power they inherited from Isaac, which was the blessing to live by the sword [רש"י, רבנו בחיי, שפתי כהן].

This threat was also grounded in the harsh reality of the region. The local population was prone to bloodshed, and there was a genuine danger that any minor disagreement between an Edomite and an Israelite would instantly escalate into deadly violence [ספורנו]. Underlying this hostility was Edom's awareness of the ancient prophecy that the older nation would eventually serve the younger. Driven by this knowledge, they constantly sought opportunities to strike at the Israelites before that era of subjugation could begin [ביאור יש"ר]. Ultimately, Edom's militant reaction to a sincere offer of peace perfectly embodies the dynamic of one side seeking harmony while the other is strictly prepared for war [קיצור בעל הטורים].
