Ecclesiastes contains the writings of a wealthy Jew who suffered from the sorrows and disappointments of life and now tries to discover the true value and meaning of life through God. The author of this book calls himself "The Preacher," "The son of David," and "king in Jerusalem." But whether this was Solomon or a later "son of David" is uncertain.

Ecclesiastes 3

3:11 He 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.
