'Fool' in the Bible

The wise man’s eyes are in his head, but the fool walks in darkness. And yet I know that one fate befalls them both.

Then I said to myself, “As is the fate of the fool, it will also befall me. Why then have I been extremely wise?” So I said to myself, “This too is vanity.”

For there is no lasting remembrance of the wise man as with the fool, inasmuch as in the coming days all will be forgotten. And how the wise man and the fool alike die!

And who knows whether he will be a wise man or a fool? Yet he will have control over all the fruit of my labor for which I have labored by acting wisely under the sun. This too is vanity.

The fool folds his hands and consumes his own flesh.

For the dream comes through much effort and the voice of a fool through many words.

For what advantage does the wise man have over the fool? What advantage does the poor man have, knowing how to walk before the living?

For as the crackling of thorn bushes under a pot,So is the laughter of the fool;And this too is futility.

Do not be excessively wicked and do not be a fool. Why should you die before your time?

Even when the fool walks along the road, his sense is lacking and he demonstrates to everyone that he is a fool.

Words from the mouth of a wise man are gracious, while the lips of a fool consume him;

Yet the fool multiplies words. No man knows what will happen, and who can tell him what will come after him?

The toil of a fool so wearies him that he does not even know how to go to a city.
