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 1

1:13 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.
