'Sand' in the Bible

And every one that heareth these words of mine, and doeth them not, shall be likened unto a foolish man, who built his house upon the sand:

And Isaiah crieth concerning Israel, If the number of the children of Israel be as the sand of the sea, it is the remnant that shall be saved:

wherefore also there sprang of one, and him as good as dead,'so many as the stars of heaven in multitude, and as the sand, which is by the sea-shore, innumerable.

and he 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 on his horns ten diadems, and upon his heads names of blasphemy.

and shall come forth 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.
