'Madness' in the Bible

And I give my heart to know wisdom, and to know madness and folly: I have known that even this is vexation of spirit;

And I turned to see wisdom, and madness, and folly, but what is the man who cometh after the king? that which is already -- they have done it!

I have turned round, also my heart, to know and to search, and to seek out wisdom, and reason, and to know the wrong of folly, and of foolishness the madness.

This is an evil among all that hath been done under the sun, that one event is to all, and also the heart of the sons of man is full of evil, and madness is in their heart during their life, and after it -- unto the dead.

The beginning of the words of his mouth is folly, And the latter end of his mouth Is mischievous madness.
