All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing.

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.

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 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.

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.

Keep thy foot when thou goest to the house of God, and be more ready to hear, than to give the sacrifice of fools: for they consider not that they do evil.

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.

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

It is better to go to the house of mourning, than to go to the house of feasting: for that is the end of all men; and the living will lay it to his heart.

Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.

The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.

It is better to hear the rebuke of the wise, than for a man to hear the song of fools.

Surely oppression maketh a wise man mad; and a gift destroyeth the heart.

Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:
