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

9:2 All things come alike to all: there is one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as is the good, so is the sinner; and he that sweareth, as he that feareth an oath.
