Ecclesiastes 2:15-19

Then I said in my heart, “What happens to the fool will happen to me also. So to what advantage is my wisdom?” Then I said to myself, “This also is vanity.” For there is no lasting memory for the wise or the fool, by which in the coming days everyone will be forgotten. How the wise dies just like the fool! And I began to hate life for the labor that was done under the sun was contemptible to me, for all of this was vanity and chasing the wind. And I despised all the toil in which I labored under the sun, which I will give up to the man who comes after me. And who knows if this man will be wise or a fool? Yet he will gain power over every labor that I have toiled and my use of wisdom under the sun. Also this is vanity.
