'Stupidity' in the Bible

My lord should pay no attention to this worthless man Nabal, for he lives up to his name: His name is Nabal, and stupidity is all he knows. I, your servant, didn’t see my lord’s young men whom you sent.

He will die because there is no discipline,and be lost because of his great stupidity.

A shrewd person conceals knowledge,but a foolish heart publicizes stupidity.

Every sensible person acts knowledgeably,but a fool displays his stupidity.

The sensible man’s wisdom is to consider his way,but the stupidity of fools deceives them.

I turned my thoughts to know, explore, and seek wisdom and an explanation for things, and to know that wickedness is stupidity and folly is madness.
