The sudden collapse of a mighty, seemingly invincible regional power sends shockwaves of terror and despair across neighboring nations. As the great city of Tyre falls, the nearby Philistine cities witness the destruction and are struck with deep anxiety, realizing their own doom is near. Ashkelon and Gaza are gripped by intense trembling and shuddering as they watch the ruin unfold [מצודת ציון]. These cities are mentioned specifically because of their proximity to the land of Israel, serving to highlight a sharp contrast with Jerusalem, which is destined to dwell in absolute safety [אבן עזרא]. The bond between the Philistine cities and Tyre goes beyond mere geography; they were close allies [מלבי״ם] whose economies similarly depended on international trade [ביאור שטיינזלץ].
At the heart of their despair is a profound sense of shame and shattered expectations. The primary approach among commentators is that Tyre served as the ultimate support and hope for the Philistines. They constantly looked toward it for help and salvation, relying on its immense power and high status among the nations. However, when they see Tyre destroyed and exiled by God, their great hope is bitterly disappointed, leaving them humiliated and ashamed [רש״י, רד״ק, אברבנאל, מצודת דוד]. Alternatively, another tradition suggests that the shame experienced by the city of Ekron does not stem directly from the fall of Tyre, but rather from its own excessive self-confidence that ultimately proves false [רד״ק]. Interestingly, while Ekron was historically a Philistine city, ancient sages drew a spiritual connection between it and Edom, identifying it with the city of Caesarea [רש״י, אברבנאל].
Ultimately, this chain of destructive events leads the Philistine cities to surrender to Israel [רד״ק, אברבנאל]. Each city faces a grim, specific fate. Gaza will lose its sovereignty and the ruler who governs it. Even if the city is resettled in the future, it will never again rise as an independent kingdom with a king of its own [מלבי״ם]. Ashkelon faces an even harsher reality, as it is destined to become a complete wasteland, entirely emptied of its people [מצודת דוד, ביאור שטיינזלץ]. Yet, another perspective offers a slight variation, suggesting that Ashkelon will not remain desolate forever. Instead, it will only be cleared of its original inhabitants in order to make room for the future settlement of the people of Israel [רד״ק].
