It spake with my heart, saying, Behold, I was magnified, and added wisdom over all that were before me at Jerusalem: and my heart saw much of wisdom and knowledge.

For there is man his labor in wisdom, and in knowledge and in success; and to man not laboring in it he shall give his portion. Also this is vanity and much evil.

The sleep of the servant is sweet, if little, or if much he shall eat: and the satiety to the rich not permitting to him to sleep.

Also all his days in darkness shall he eat, and much vexation and his sickness and his anger.

For he shall not much remember the days of his life; for God humbles him in the gladness of his heart.

There is evil which I saw under the sun, and it is much upon man:

Wisdom is good above the instruments of encounter: and one sinning will destroy much good.

And besides, from these, my son, beware: of making many books, no end; and much study wearies the flesh.
