'Fools' in the Bible

Surely the princes of Zoan are fools, the counsel of the wise counsellers of Pharaoh is become brutish: how say ye unto Pharaoh, I am the son of the wise, the son of ancient kings?

The princes of Zoan are become fools, the princes of Noph are deceived; they have also seduced Egypt, even they that are the stay of the tribes thereof.

And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein.
