'Fools' in the Bible

The princes of Zoan are mere fools;The advice of Pharaoh’s wisest advisers has become stupid.How can you men say to Pharaoh,“I am a son of the wise, a son of ancient kings”?

A highway will be there, a roadway,And it will be called the Highway of Holiness.The unclean will not travel on it,But it will be for him who walks that way,And fools will not wander on it.

Causing the omens of boasters to fail,Making fools out of diviners,Causing wise men to draw backAnd turning their knowledge into foolishness,
