Ecclesiastes 3:10-12

¹⁰I have seen the travail, which God hath given to the sons of men to be exercised in it.

¹¹He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.

¹²I know that there is no good in them, but for a man to rejoice, and to do good in his life.
