And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.

I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.

And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

I said in mine heart, Go to now, I will prove thee with mirth, therefore enjoy pleasure: and, behold, this also is vanity.

I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what was that good for the sons of men, which they should do under the heaven all the days of their life.

I got men-servants, and maid-servants, and sons of the house were to me; also, I had much substance -- herd and flock -- above all who had been before me in Jerusalem.

And whatsoever mine eyes desired I kept not from them, I withheld not my heart from any joy; for my heart rejoiced in all my labour: and this was my portion of all my labour.

Then I examined all of my accomplishments that I had brought about by my own efforts, including the work that I had labored so hard to complete and it was all pointless, like chasing after the wind, and there was nothing to be gained on earth.

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

So I loathed all the fruit of my effort, for which I worked so hard on earth, because I must leave it behind in the hands of my successor.

Therefore I went about to cause my heart to despair of all the labour which I took under the sun.

For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun?

For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.

He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.

I said in mine heart, God shall judge the righteous and the wicked: for there is a time there for every purpose and for every work.

I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.

Be not rash with thy mouth, and let not thine heart be hasty to utter any thing before God: for God is in heaven, and thou upon earth: therefore let thy words be few.

There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt.

I have seen personally what is the only beneficial and appropriate course of action for people: to eat and drink, and find enjoyment in all their hard work on earth during the few days of their life which God has given them, for this is their reward.

For he shall not much remember the days of his life; because God answereth him in the joy of his heart.

There is an evil which I have seen under the sun, and it is hard on men;

God gives a man wealth, possessions, and honor, so that he lacks nothing his heart desires; yet God does not enable him to enjoy it--instead someone else ends up enjoying it. This [is] vanity--indeed, it [is] a grievous ill!
