“Was Jesus a Palestinian?”
The word “Palestine” has an interesting etymology. It appears five centuries before Christ in the secular history of the Greek Herodotus as Palaistínē [Παλαιστίνη]. The similarities to our modern noun are obvious. The Greek word in turn derives from pᵊlištî, a Hebrew word that appears as early as Genesis.
Other ancient languages like Akkadian and Egyptian had similar constructions, so it’s probable Hebrew simply transliterated it from another local tongue as “Philistine”. To the Hebrews it meant “immigrant”, to the Egyptians “sea people”.
