'Sand' in the Bible

I will richly bless thee, and greatly multiply thy seed, as the stars of heaven, and as the sand that is on the sea-shore; and thy seed shall possess the gate of his enemies;

And thou saidst, I will certainly deal well with thee, and make thy seed as the sand of the sea, which cannot be numbered for multitude.

And Joseph laid up corn as sand of the sea exceeding much, until they left off numbering; for it was without number.
