'Madness' in the Bible

And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

I said about laughter, “It is madness,” and about pleasure, “What does this accomplish?”

And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been already done.

I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:

This is an evil among all things that are done under the sun, that there is one event unto all: yea, also the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead.

The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.
