'Pits' in the Bible

And they said not, Where is Jehovah, that brought us up out of the land of Egypt, that led us in the wilderness, in a land of deserts and of pits, in a land of drought and of the shadow of death, in a land that no one passeth through, and where no man dwelleth?

And their nobles send their little ones for water: they come to the pits, they find no water; they return with their vessels empty; they are ashamed, they are confounded, and have covered their heads.
