Ecclesiastes 2:15-17

¹⁵And I said in my heart, As the event of the fool is, So shall it be to me, even to me; And to what purpose have I gained wisdom? I said moreover in my heart, This is also vanity, Because the fool speaks of his abundance.

¹⁶For there is no remembrance of the wise man With the fool forever; Forasmuch as now in the coming days All things are forgotten: And how shall the wise man die with the fool?

¹⁷So I hated life; Because the work that was wrought under the sun Was evil before me: For all is vanity and waywardness of spirit.
