'Fool' in the Bible

The wise use their eyes, but the fool walks in darkness. I also perceived that the same outcome affects them all.

Then I told myself, "Whatever happens to the fool will happen also to me. Therefore what's the point in being so wise?" And I told myself that this also is pointless.

For neither the wise nor the fool will be long remembered, since in days to come everything will be forgotten. The wise man dies the same way as the fool, does he not?

The fool crosses his arms and starves himself.

Too many worries lead to nightmares, and a fool is known from talking too much.

For what advantage has the wise person over the fool? What advantage does the poor man have in knowing how to face life?

For as thorns burn to heat a pot, so also is the laughter of the fool even this is pointless.

Do not excel at wickedness, nor be a fool. Why die before your time?

Furthermore, the way a fool lives shows he has no sense; he proclaims to everyone that he's a fool.

The words spoken by the wise are gracious, but the lips of a fool will devour him.

The fool overflows with words, and no one can predict what will happen. As to what will happen after him, who can explain it?

The work of a fool so wears him out that he can't even find his way to town.
