Moses dispatches a carefully crafted diplomatic message to the king of Edom, seeking safe passage for the Israelites on their journey to Canaan. The appeal is designed to soothe any anxieties regarding military conquest, economic disruption, or territorial ambitions, while subtly weaving in profound historical and spiritual undertones.
The appeal for passage rests on a shared family history. Because Esau and his descendants in Edom did not endure the Egyptian exile or pay the debt of servitude decreed upon Abraham's lineage, they have no grounds to contest the Israelites' inheritance of the Land of Israel. The least they can do is offer the minor assistance of allowing them to cross their territory [רש"י, רבנו בחיי, אדרת אליהו]. The request is framed to emphasize that this is a strictly temporary transit, reassuring Edom that there is no intention to conquer or annex their land [בכור שור, פני דוד]. Furthermore, the appeal is meant to evoke Esau's ancient invitation to Jacob to journey together, hoping to awaken a dormant sense of brotherhood [הטור הארוך, קיצור בעל הטורים].
To prove their peaceful intentions, the Israelites vow to avoid fields and vineyards. They commit to not acting like thieves or spies creeping along the outskirts of cities [שפתי כהן], ensuring they will not trample or ruin the local harvest [רלב"ג, אבן עזרא, ספורנו]. They even promise to muzzle their livestock to prevent them from grazing on roadside vegetation [רש"י]. Staying out of the fields also serves a legal purpose, ensuring the Israelites do not inadvertently establish any formal claim of ownership over the land by treading on it or cutting its branches [פני דוד].
Recognizing that water is a precious and scarce resource in the region [רשב"ם, העמק דבר], the Israelites swear not to drink from private wells that the locals labored to dig, relying instead only on free-flowing rivers [חזקוני]. The primary approach among commentators notes that they specifically refer to a flowing well rather than a stagnant cistern; even though a well constantly replenishes itself, the Israelites refuse to benefit from it without payment [כלי יקר]. Another perspective suggests they are actually referring to their own miraculous water supply. Despite possessing an abundance of water and manna, they commit to purchasing provisions from Edom at full price. This imparts a lesson in proper etiquette: a guest, even when fully provisioned, should buy from their host to grant them an economic benefit [רש"י, שפתי כהן, צאינה וראינה, משכיל לדוד].
Outlining their exact route, the Israelites pledge to travel exclusively along the main public artery [רשב"ם, ביאור יש"ר, ביאור שטיינזלץ], or along a specific path dictated by the king of Edom and led by his personal guide [ספורנו, אבן עזרא]. Marching openly on a main road proves they have no plans to fan out into vulnerable villages to plunder [מלבי"ם] or to sneak through hidden, winding trails [אם למקרא]. On a spiritual level, remaining on the main highway signifies that they are walking in the path of the King of the Universe, God, and will not deviate from His strict command forbidding them to provoke Edom [שפתי כהן, אדרת אליהו].
Finally, Moses defines the timeframe of their passage, stating it will last only until they clear Edomite borders. He deliberately avoids mentioning their final destination. This omission is calculated to prevent arousing the king's jealousy or reminding him of the birthright Jacob deceitfully took from Esau, which could provoke Edom to claim the land as their own [רבנו בחיי, הטור הארוך]. Yet, this phrasing also conceals a prophetic hint. The vow to avoid conflict and stay on the path applies strictly to this present journey. In the distant Messianic future, the Israelites are destined to return to judge and subdue the mountain of Esau [אור החיים, שפתי כהן].
