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.

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

There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.

There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt.

And this also is a sore evil, that in all points as he came, so shall he go: and what profit hath he that hath laboured for the wind?

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

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

Therefore remove sorrow from thy heart, and put away evil from thy flesh: for childhood and youth are vanity.
