'Madness' in the Bible

The Lord will strike you with madness and with blindness and with bewilderment of heart and mind;

And I set my mind to know [practical] wisdom and to discern [the character of] madness and folly [in which men seem to find satisfaction]; I realized that this too is a futile grasping and chasing after the wind.

So I turned to consider [secular] wisdom, madness, and folly; for what will the man do who succeeds the king? Nothing except what has already been done.

I turned around and directed my heart to know, to investigate and to seek [skillful and godly] wisdom and the reason for things, and to know that wickedness is folly and that foolishness is madness [leading to stupidity and recklessness].

This evil is in all that is done under the sun, that one fate comes to all. Also, the hearts of the sons of men are full of evil, and madness is in their hearts while they live, and afterwards they go to the dead.

the beginning of his talking is foolishness and the end of his talk is wicked madness.

In that day,” declares the Lord, “I will strike every horse with panic and his rider with madness; but I will open My eyes and watch over the house of Judah, and will strike every horse of the [opposing] nations with blindness.
