'Sands' in the Bible

And the Philistines came together to make war on Israel, three thousand war-carriages and six thousand horsemen and an army of people like the sands of the sea in number: they came up and took up their position in Michmash, to the east of Beth-aven.

But my suggestion is that all Israel, from Dan as far as Beer-sheba, comes together to you, a great army like the sands of the sea in number; and that you yourself go out among them.

They are coming all of them with force; the direction of their faces is forward, the number of their prisoners is like the sands of the sea.

When it was full, they took it up on the sands; and seated there they put the good into vessels, but the bad they put away.

And will go out to put in error the nations which are in the four quarters of the earth, Gog and Magog, to get them together to the war, the number of whom is like the sands of the sea.
