'Seacoast' in the Bible

therefore thus saith the Lord Jehovah: Behold, I stretch out my hands upon the Philistines, and I will cut off the Kerethites, and cause the remnant of the sea-coast to perish.

Woe unto the inhabitants of the sea-coast, the nation of the Cherethites! The word of Jehovah is against you, O Canaan, land of the Philistines: I will destroy thee, that there shall be no inhabitant;

and the sea-coast shall be cave-dwellings for shepherds, and folds for flocks.
