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 7:23-26
"All this have I proved by wisdom: I said, I will be wise; but it was far from me. That which is far off, and exceeding deep, who can find it out? I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness: and I find more bitter than death the woman, whose heart is snares and nets, and her hands as bands: whoso pleaseth God shall escape from her; but the sinner shall be taken by her"
