'Sand' in the Bible

that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heavens, and as the sand which is upon the seashore. And thy seed shall possess the gate of his enemies.

And thou saidst, I will surely do thee good, and make thy seed as the sand of the sea, which cannot be numbered for multitude.

And Joseph laid up grain as the sand of the sea, very much, until he left off numbering; for it was without number.
