בראשית, פרק כ״ו, פסוק כ״ט

Abimelech and the Philistine delegation arrive to secure a peace treaty with Isaac, utilizing cunning political rhetoric to reframe their past expulsion of him as an act of kindness. Their objective is strictly a non-aggression pact, rather than an alliance of mutual defense or friendship [מלבי״ם, העמק דבר]. This diplomatic mission is driven by a deep fear of Isaac's growing power. The Philistines worry that, following his harsh dismissal, he might void the historic peace treaty forged with his father, Abraham, or even launch a military campaign against them [רמב״ן, הטור הארוך, חזקוני].

To persuade Isaac, the delegation attempts to justify their previous behavior by claiming they only ever protected him. They remind him that during his stay, the king issued a royal decree to shield him and his wife from the hostile local mob [רמב״ן, הטור הארוך, ביאור יש״ר]. The primary approach among commentators is that the Philistines view the very act of expelling Isaac without violence or confiscating his enormous wealth as a profound favor. In an era where it was customary to seize the assets of affluent foreigners, they frame his safe departure as an act of grace. Several commentators illustrate the deep cynicism of this argument using the parable of a bird that pulls a bone from a lion's throat. When the bird asks for a reward, the lion replies that safely removing its head from the beast's jaws is reward enough. Similarly, the Philistines boast that sparing Isaac's life and property was a monumental kindness, considering their natural inclination was to plunder vulnerable strangers [פענח רזא, הדר זקנים, דעת זקנים, ברכת אשר].

Building on this distorted narrative, the delegation demands reciprocity. They argue that just as they supposedly showed kindness by sending him away peacefully, he is now obligated to formalize a treaty and deal kindly with them [רש״י, רשב״ם, מזרחי, גור אריה, שפתי חכמים]. Furthermore, they point to his current prosperity as absolute proof that their expulsion caused him no harm whatsoever [בכור שור, ביאור יש״ר, מלבי״ם].

On a much deeper level, their appeal reveals a profound shift in their perspective and an admission of past mistakes. When Isaac first amassed his wealth among them, the Philistines were consumed by jealousy, assuming his business success was simply the result of exploiting their land and resources. However, after banishing him to an isolated region and watching his prosperity only multiply, they are forced to concede that his wealth does not depend on their local economy. Instead, they recognize it stems from direct divine providence and that he is personally blessed by God [אור החיים, בית הלוי, חתם סופר]. It is this undeniable realization of his divine backing and supernatural success that ultimately compels them to initiate a lasting peace.
