I spoke within my own heart, saying, Lo, I have become great and have gathered more wisdom than all that have been before me in Jerusalem; yea, my heart has seen much of wisdom and knowledge.

For in much wisdom is much grief; and he who increases knowledge increases sorrow.

The sleep of a laboring man is sweet, whether he eats little or much; but the abundance of the rich will not allow him to sleep.

Also all his days he eats in darkness, and he has much sorrow and wrath with his sickness.

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

Wisdom is better than weapons of war; but one sinner destroys much good.

And further, by these, my son, be warned: The making of many books has no end, and much study is a weariness of the flesh.
