... a distinctive Aegean-style material culture associated with the Philistines
Rabbinic sources insist that the Philistines of Judges and Samuel were different people altogether from the Philistines of Genesis. (Midrash Tehillim on Psalm 60 (Braude: vol. 1, 513); the issue here is precisely whether Israel should have been obliged, later, to keep the Genesis treaty.) This parallels a shift in the Septuagint's translation of Hebrew pĕlištim. Before Judges, it uses the neutral transliteration phulistiim, but beginning with Judges it switches to the pejorative allophuloi. [Footnote 26: To be precise, Codex Alexandrinus starts using the new translation at the beginning of Judges and uses it invariably thereafter, Vaticanus likewise switches at the beginning of Judges, but reverts to phulistiim on six occasions later in Judges, the last of which is 14:2.]
Little is known of the Philistine language or script. There is never any indication in the Bible of a language problem between the Israelites and Philistines. The Philistines must have adopted the indigenous Semitic language soon after arriving in Canaan, or they might have already known a Semitic language before they came. Their names are usually Semitic (e.g., Ahimelek, Mitinti, Hanun, and the god Dagon). But two Philistine names may have come from the Asianic area: Achish has been compared with Anchises, and Goliath with Alyattes. A few Hebrew words may be Philistine loanwords. The word for helmet (koba H3916 or qoba H7746) is a foreign word often attributed to the Philistines. The term for "lords," already mentioned (seren), can possibly be connected with tyrannos ("tyrant"), a pre-Greek or Asianic word. Some have connected three seals discovered in the excavations at Ashdod with the Philistines. The signs resemble the Cypro-Minoan script. Three inscribed clay tablets from Deir Alla (SUCCOTH) also have been attributed to the Philistines. These signs resemble the Cypro-Mycenaean script. Both the seals and clay tablets are still imperfectly understood.
According to biblical tradition (Deuteronomy 2:23; Jeremiah 47:4), the Philistines came from Caphtor (possibly Crete, although there is no archaeological evidence of a Philistine occupation of the island.)
