Insanity

He that passeth by, and meddleth with strife belonging not to him, is like one that taketh a dog by the ears.

As a mad man who casteth firebrands, arrows, and death,

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 words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself.

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