'Sea' in the Bible

"I will destroy humanity and beast; I will destroy the birds of the sky and the fish of the sea, and the stumbling blocks with the wicked. And I will cut off humankind from the face of the earth"--a declaration of Yahweh.

Woe [to you], inhabitants of the region of the sea, people of the Kerethites! The word of Yahweh [is] against you, O Canaan, land of the Philistines. I will destroy you {until there is no inhabitant}.

And you, O region of the sea, shall become pastures [and] meadows [for] shepherds and sheep pens [for the] flocks.
