'Fool' in the Bible
The wise man's eyes are in his head, and the fool walks in darkness -- and yet I perceived that one event happens to them all.
Then I said in my heart, "As it happens to the fool, so will it happen even to me; and why was I then more wise?" Then I said in my heart that this also is vanity.
For of the wise man, even as of the fool, there is no memory for ever, since in the days to come all will have been long forgotten. Indeed, the wise man must die just like the fool!
Who knows whether he will be a wise man or a fool? Yet he will have rule over all of my labor in which I have labored, and in which I have shown myself wise under the sun. This also is vanity.
For what advantage has the wise more than the fool? What has the poor man, that knows 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.
Yes also, when the fool walks by the way, his understanding fails him, and he says to everyone that he is a fool.
The words of a wise man's mouth are gracious; but a fool is swallowed by his own lips.
A fool also multiplies words. Man doesn't know what will be; and that which will be after him, who can tell him?
