The Philistines: Prophecies Respecting: Utter Destruction by Pharaoh King of Egypt

This is the word of the LORD that came to Jeremiah the prophet about the Philistines before Pharaoh struck down Gaza. …

Woe to the dwellers of the seacoast, O nation of the Cherethites! The word of the LORD is against you, O Canaan, land of the Philistines: “I will destroy you, and no one will be left.”

So the seacoast will become a land of pastures, with wells for shepherds and folds for sheep.
