'Sands' in the Bible

And he took up a position upon the sands of the sea-shore. Then I saw a Wild Beast coming up out of the sea, and he had ten horns and seven heads. On his horns were ten kingly crowns, and inscribed on his heads were names full of blasphemy.

and will go out to lead astray the nations in all the four corners of the earth, Gog and Magog, and assemble them for war, and they are like the sands on the seashore in number.
