'Insanity' in the Bible

The LORD will afflict you with insanity, blindness, and mental confusion.

So I dedicated myself to learn about wisdom and knowledge, and about insanity and foolishness. And I discovered that this is also like chasing after the wind.

Next I turned to examine wisdom, insanity, and foolishness, because what can a person do who succeeds the king except what has already been accomplished?

At that time,' declares the LORD, "I will strike every horse with panic and every rider with insanity. I will keep my eyes on the house of Judah, but I will blind every horse of the invading armies.
