'Grains' in the Bible

So in fact children were fathered by one man -- and this one as good as dead -- like the number of stars in the sky and like the innumerable grains of sand on the seashore.

and will go out to deceive the nations at the four corners of the earth, Gog and Magog, to bring them together for the battle. They are as numerous as the grains of sand in the sea.
