All the rivers flow toward the sea, but the sea is never full; then rivers return to the headwaters where they began.

All things are full of weariness; man may not give their story: the eye has never enough of its seeing, or the ear of its hearing.

Whenever I wanted something I had seen, I never refused that desire. Instead, I enjoyed everything I did, and this became the reward in what I had undertaken.

Forsomuch as a man should weary himself with wisdom, with understanding and opportunity, and yet be fain to leave his labours unto another, that never sweat for them. This is also a vain thing and a great misery.

But better off than both of them is the one who has never existed, who has never seen the evil activity that is done under the sun.

There was a certain man without a dependent, having neither a son nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “And for whom am I laboring and depriving myself of pleasure?” This too is vanity and it is a grievous task.

He who has a love for silver never has enough silver, or he who has love for wealth, enough profit. This again is to no purpose.

When I gave my heart to know wisdom and to see the task which has been done on the earth (even though one should never sleep day or night),

Furthermore, their love, their hate, and their envy have been long lost. Never again will they have a part in what happens on earth.

Let your clothes be white all the time, and never let oil be lacking on your head.
