'Fool' in the Bible

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

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

For there is no remembrance of the wise more than of the fool for ever; seeing that which now is in the days to come shall all be forgotten. And how dieth the wise man? as the fool.

And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.

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

For what hath the wise more than the fool? what hath the poor, that knoweth 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.

Yea also, when he that is a fool walketh by the way, his wisdom 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 is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?
