Και η wikipedia συμφωνεί για τη συγγένεια Ελλήνων και Φιλισταίων (αρχαίων Παλαιστινίων)

The Philistines (Hebrew פלשתים, plishtim) (see "other uses" below) were a people who occupied the southern coast of Canaan, their territory being named Philistia in later contexts. Their origin has been debated among scholars. The Philistine language has been identified as a Semitic language but modern archaeology has also suggested early cultural links with the Mycenean world in mainland Greece.[1] Though the Philistines adopted local Canaanite culture and language before leaving any written texts, an Indo-European origin has been suggested for a handful of known Philistine words (see Philistine language).
