'Fool' in the Bible

The wise man's eyes are in his head, and the fool walketh in darkness: and yet I perceived that one event happeneth to them all.

Then said I in my heart, As it happeneth to the fool, so will it happen even to me; and why was I then more wise? Then said I in my heart, that this also is vanity.

For of the wise man, even as of the fool, there is no remembrance for ever; seeing that in the days to come all will have been long forgotten. And how doth the wise man die even as the fool!

And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity.

The fool foldeth his hands together, and eateth his own flesh.

For a dream cometh with a multitude of business, and a fool's voice with a multitude of words.

For what advantage hath the wise more than the fool? or what hath the poor man, that knoweth how to walk before the living?

For as the crackling of thorns under a pot, so is the laughter of the fool: this also is vanity.

A wise man's heart is at his right hand; but a fool's heart at his left.

Yea also, when the fool walketh by the way, his understanding faileth him, and he saith to every one that he is a fool.

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

A fool also multiplieth words: yet man knoweth not what shall be; and that which shall be after him, who can tell him?
