The Hebrew Bible describes constant warfare between the Jews and other tribes, including the Philistines, whose capital was Gaza.
And no arabs around.
The Philistines were the ancient ancestors of the Palestinian people who are now also called arabs.
Not sure that that is totally accurate, Sunni...
I recently read
“The Oxford History of the Biblical World,” edited by Dr. Michael D. Coogan, director of publications for the Harvard Semitic Museum and expert in Near Eastern languages and literatures. The book is excellent on Syria-Palestinian archeology.
The following will shed light on the question.
The end of the
thirteenth century BCE saw major disruptions in the civilizations of the Near East, Cyprus and Greece for unclear reasons (possible major droughts). “Many populations appear to have migrated….Egypt was attacked by groups called
‘Sea Peoples.’ They were repelled from Egypt, but the Egyptians could not stop them from taking over the Canaan coast.
The Philistines …were among the Sea Peoples.”
“…the Philistines did not occupy the coast of Canaan until the twelfth century BCE…”
“Not long before, another group had appeared in the land of Canaan…This group called itself Israel…The Egyptians maintained some control over parts of Canaan until just after the death of Rameses III in 1153 BCE….[including] Canaanites, Egyptians, Israelites, and
the mysterious ‘Sea Peoples,’ of whom the Philistines are the best known. The settlement process in highland Israel began a generation or two before the Sea Peoples arrived on the coast…The displacement and migration of the tribe of Dan from the central coast to the far north is symptomatic of …this event.”
“This movement is documented by a variety of written sources in Akkadian, Ugaritic, Egyptian, and Hebrew, by Egyptian wall reliefs and by archeology.”
“The Philistines bequeathed their own name to Philistia (and later to all of Palestine).”
“Cypriot archaeologists invoke the Achaeans or Danaoi of Homeric epic as the agents of culture change in Cyprus; in the Levant, the same change is ascribed to the Sea Peoples. Both agents participated in the event recorded by Rameses III and should be related to the same confederacy of
Sea Peoples, or Mycenaean Greeks, who invaded the coastlands of (Cyprus) around 1185-1175.”
Further evidence of the origin of the Philistines can be seen in biblical texts, which indicate expert bowman, “chariot-warriors,” and “chariots of iron,” (I Samuel 31.3, Judg. 1.18-19) and pottery which show warriors armed like the Mycenaean warriors depicted on the famous “Warrior Vase” found in Mycenae. The description fits Goliatath, as in I Samuel 17.5-6.
Under King David, first quarter of the tenth century, the Philistines were driven back to their original coastal cities.
So, it seems that the Philistines are the 'mysterious Sea People' who came from Greece or Cyprus...and Egypians, Israelites, etc here in place prior to the event.
Further, what we call 'arabs' merely means any people who speak arabic.
"In general, the term "Arab" in modern times is applied to a large group of different peoples that share in common the Arabic language,..."
