The Edomites also were the Philistines and lived on the shore of the Mediterranean and branched out from there, too, by sea.

You've got a rather large number of things mixed up. The Philistines were (or at least were ruled by) a completely non-Semitic group, probably related to the Myceneans run out of Greece by the Dorians and other invading Greek tribes.

There is also little or no evidence that the Philistines were a seafaring people, at least once they reached Palestine. You may be confusing them with the Phoenicians, who were another Semitic people, essentially northern Canaanites, and who spoke a Semitic language almost identical to Hebrew.

Some of the other ethic groups in the area included Ammonites, Moabites, Hittites, Amorites, etc. There were a lot of different groups around.

Extra points if you can figure out the only one still extant!

Psalms 60:8
"Moab is My washbowl;
Over Edom I shall throw My shoe;
Shout loud, O Philistia, because of Me!"

They were all the same peoples with different chiefs.
