בראשית, פרק י׳, פסוק י״ד

The lineage of Egypt branches out into various ancient nations, carrying with it a complex web of geographic and genetic origins. A particular focus falls on the emergence of the Philistine people, whose roots are deeply intertwined with several distinct groups. Among the descendants of Egypt are the Pathrusim, who likely resided in the Pathros region of Upper Egypt [שד״ל, קאסוטו]. Another group is the Casluhim, whose exact geographic location remains somewhat of a mystery [שד״ל], though they may have lived in Asia Minor or around Mount Casius [קאסוטו]. A third group, the Caphtorim, is widely identified with the inhabitants of the island of Crete [שד״ל, שטיינזלץ, קאסוטו], while others place them in the region of Cappadocia [העמק דבר, נתינה לגר] or the Damietta area in Egypt [רד״ק, מחוקקי יהודה]. Interestingly, the Caphtorim were known to be a nation of particularly short people [העמק דבר]. By being listed as direct descendants of Egypt, it emphasizes that these nations carried the core strength and image of their founding father [אבן עזרא, מחוקקי יהודה].

The precise origin of the Philistines is a subject of deep discussion. The primary approach among commentators is that they did not emerge from just one group, but rather from a blending of both the Pathrusim and the Casluhim. Ancient Midrashic tradition explains that these two groups would frequently swap wives with one another, and the Philistine nation was born from these mixed unions [רש״י, רבנו בחיי, אם למקרא]. God specifically detailed this Egyptian lineage to serve as a warning for the Israelites. Since the Israelites harbored deep resentment toward the Egyptians who had enslaved them, God wanted them to recognize the Philistines' Egyptian roots and distance themselves from their ways as well [שד״ל].

A historical puzzle arises when comparing this origin story to the later prophetic books, which explicitly state that the Philistines came from Caphtor. To resolve this, some suggest that a faction of the Casluhim had been living in the land of Caphtor. They eventually left, conquered new territory, and became known as the Philistines [ביאור יש״ר, מחוקקי יהודה]. The name of the Philistines itself is rooted in the concepts of exile and wandering [שד״ל].

From a historical perspective, the Philistines were part of the Sea Peoples who arrived from across the Mediterranean [שטיינזלץ]. This suggests there were likely multiple waves of migration. The first wave, which the early Israelite Patriarchs encountered, originated from the Casluhim and settled peacefully in the southern region of the Negev. A later, more aggressive wave arrived from the island of Caphtor, eventually establishing the powerful military state ruled by the Philistine lords during the era of the Judges [קאסוטו]. Other perspectives suggest that the Philistines and the Caphtorim were simply one and the same nation [אם למקרא], or that the Philistines were actually the result of a complete merger of all three groups, namely the Pathrusim, Casluhim, and Caphtorim [רד״ק, שד״ל]. Ultimately, despite their Egyptian ancestry, they chose to wander and settle in the land of Canaan because the land of Egypt proved unsuitable for them [רד״ק].
