'Sand of the Sea' in the Bible

But Isaiah crieth out concerning Israel, "Though the number of the sons of Israel be as the sand of the sea, only the remnant will be saved.

And I stood upon the sand of the sea. And I saw a beast coming up out of the sea, having ten horns and seven heads, and upon his horns ten diadems, and upon his heads names of blasphemy.

and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war, the number of whom is as the sand of the sea.
