The twenty-first Book in the Bible is Ecclesiastes. The word Ecclesiastes means "a speaker at an assembly". There is only one speaker in the book - The Teacher. Ecclesiastes is the sharing of one man's search for satisfaction in life, in which we discover that without God there is no meaning to be found. The Teacher wants to spare his readers the harsh lessons which he has himself learned.
Ecclesiastes 9:14-17
"there was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it: now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man. Then said I, Wisdom is better than strength: nevertheless the poor man’s wisdom is despised, and his words are not heard. The words of wise men are heard in quiet more than the cry of him that ruleth among fools"
