'Fool' in the Bible

The wise! -- his eyes are in his head, and the fool in darkness is walking, and I also knew that one event happeneth with them all;

and I said in my heart, 'As it happeneth with the fool, it happeneth also with me, and why am I then more wise?' And I spake in my heart, that also this is vanity:

That there is no remembrance to the wise -- with the fool -- to the age, for that which is already, in the days that are coming is all forgotten, and how dieth the wise? with the fool!

The fool is clasping his hands, and eating his own flesh:

For the dream hath come by abundance of business, and the voice of a fool by abundance of words.

For what advantage is to the wise above the fool? What to the poor who knoweth to walk before the living?

For as the noise of thorns under the pot, So is the laughter of a fool, even this is vanity.

Do not much wrong, neither be thou a fool, why dost thou die within thy time?

The heart of the wise is at his right hand, And the heart of a fool at his left.

And also, when he that is a fool Is walking in the way, his heart is lacking, And he hath said to every one, 'He is a fool.'

He hath set the fool in many high places, And the rich in a low place do sit.

Words of the mouth of the wise are gracious, And the lips of a fool swallow him up.

And the fool multiplieth words: 'Man knoweth not that which is, And that which is after him, who doth declare to him?'
