All the rivers run into the sea, yet the sea is not full. To the place where the rivers flow, there they flow again.

All things are full of weariness beyond uttering. The eye is not satisfied with seeing, nor the ear filled with hearing.

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

For of the wise man, even as of the fool, there is no memory for ever, seeing that 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.

The fool folds his hands together and ruins himself.

For if they fall, the one will lift up his fellow; but woe to him who is alone when he falls, and doesn't have another to lift him up.

For as a dream comes with a multitude of cares, so a fool's speech with a multitude of words.

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.

This is an evil in all that is done under the sun, that there is one event to all: yes also, the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead.

A wise man's heart is at his right hand, but a fool's heart at his left.

Yes also, when the fool walks by the way, his understanding fails him, and he says to everyone that he is a fool.

He who digs a pit may fall into it; and whoever breaks through a wall may be bitten by a serpent.

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?

If the clouds are full of rain, they empty themselves on the earth; and if a tree falls toward the south, or toward the north, in the place where the tree falls, there shall it be.
