'Seacoast' in the Bible

Therefore thus saith the Lord GOD; Behold, I will stretch out mine hand upon the Philistines, and I will cut off the Cherethims, and destroy the remnant of the sea coast.

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

And the sea coast shall be dwellings and cottages for shepherds, and folds for flocks.
