And I applied my heart to seek and to search out by wisdom concerning all that is done under heaven: it is a sore travail that God hath given to the sons of men to be exercised therewith.

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

There is one that is alone, and he hath not a second; yea, he hath neither son nor brother; yet is there no end of all his labor, neither are his eyes satisfied with riches. For whom then,'saith he , do I labor, and deprive my soul of good? This also is vanity, yea, it is a sore travail.

All his days also he eateth in darkness, and he is sore vexed, and hath sickness and wrath.

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

Therefore remove sorrow from thy heart, and put away evil from thy flesh; for youth and the dawn of life are vanity.
