For a more academic treatment, please see this link for “Chapter II: Philistines - Settlement” (page 49) of Edward Lipinski’s 2006 book: “On the Skirts of Canaan in the Iron Age”.
On page 52 of this same book, we read something amazingly bold in its explicit specificity of the origins of the Philistines !!!
“It seems that the Anatolian provenance of the Philistines can be proved directly. One of the Hittites’ allies at the battle of Qadesh in 1275 B.C. was called P-d-s according to the Egyptian scribes [FN18 specifically p. 3 on P-d-s - K.A. kitchen, Ramesside Inscriptions II, Oxford 1969-79, p. 2-147]. … P-d-s is rightly taken as an equivalent of Hittite Pitassa [FN 19: G.F. del Monte - J. Tischler, Die Ortis- und Gewdssernamen der hethitischen Texte (RGTC 6), Wiesbaden 1978, p. 318-319…] , which was generally located in the area of the Salt Lake (Tuz Golu) and of the plain of Konya, but has also been equated with Pisidia. If there were several regions bearing this name, that may reappear later in Carian…, at least the Bronze Age Pitassa has to be located in West Anatolia, close to Arzawa, probably north-west of Konya, in the area of yalburt and of the present-day town of Ilgin.”] << Wow !!!
