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 9

9:5 For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
