For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

The sleep of a laboring man is sweet, whether he eateth little or much: but the abundance of the rich will not suffer him to sleep.

All his days also he eateth in darkness, and he hath much sorrow and wrath with his sickness.

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

Be not righteous over much; neither make thyself over wise: why shouldst thou destroy thyself?

Be not over much wicked, neither be thou foolish: why shouldst thou die before thy time?

Wisdom is better than weapons of war: but one sinner destroyeth much good.

By much slothfulness the building decayeth; and through idleness of the hands the house droppeth through.

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