בראשית, פרק כ״ו, פסוק כ״א

The ongoing struggle over water sources escalates from a localized dispute into a clear display of baseless hatred. In an attempt to distance themselves from the conflict and prevent further friction, Isaac's servants dig another well [מלבי״ם]. However, the Philistines arrive to fight over this new water source as well.

There is a distinct difference between the conflicts over the first and second wells. While the initial dispute might have stemmed from a genuine need for water or a perceived legal claim, the fight over the second well is entirely unjustified. The Philistines already control the first well, which provides fresh, flowing water. In contrast, the new well relies merely on collected rainwater, which is considered ownerless, meaning the Philistines have no actual need for it [מלבי״ם]. Having successfully stolen the first well using false claims, they now continue their actions without any justification, acting solely to harass and harm Isaac while local authorities turn a blind eye [העמק דבר].

Consequently, the well is named to reflect this deep-seated hatred and hostility. The Philistines act as true adversaries, relentlessly harassing Isaac and his men wherever they dig [רד״ק, ביאור יש״ר]. This repeated aggression marks a turning point in Isaac's understanding of the situation. While the first confrontation could be interpreted as a random incident or a standard legal dispute, the recurrence at the second well leaves no room for illusions. It proves beyond any doubt that he is facing intentional hatred and persecution [הדר זקנים, דעת זקנים, ברכת אשר על התורה].

This realization explains a subtle shift in the unfolding events. Previously, a specific reason was provided for the naming of the first well. Here, however, no explanation is offered. Once Isaac understands that he is dealing with blind, baseless hatred, there is no longer any point in detailing or rationalizing the cause of the quarrel [חזקוני]. Although Isaac is forced to retreat and leave the well behind, the very act of naming it serves as a declaration of ownership. Through this name, he expresses his firm stance and his refusal to surrender his rights to the land of Israel and everything within it [ברכת אשר על התורה].
