For in much [human] wisdom there is much displeasure and exasperation; increasing knowledge increases sorrow.

For the dream comes through much effort, and the voice of the fool through many words.

The sleep of a working man is sweet, whether he eats little or much; but the full stomach (greed) of the rich [who hungers for even more] will not let him sleep.

All of his life he also eats in darkness [cheerlessly, without sweetness and light], with great frustration, sickness, and anger.

For he will not often consider the [troubled] days of his life, because God keeps him occupied and focused on the joy of his heart [and the tranquility of God indwells him].

and I saw all the work of God, I concluded that man cannot discover the work that is done under the sun. Even though man may labor in seeking, he will not discover; and [more than that], though a wise man thinks and claims he knows, he will not be able to find it out.

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

But beyond this my son, [about going further than the words given by one Shepherd], be warned: the writing of many books is endless [so do not believe everything you read], and excessive study and devotion to books is wearying to the body.
