Ecclesiastes 2:19

15 So I said to myself, “The fate of the fool will also befall me. What then have I gained by being wise?” And I said to myself that this too is futile.

16 For there is no lasting remembrance of the wise, just as with the fool, seeing that both will be forgotten in the days to come. Alas, the wise man will die just like the fool!

17 So I hated life, because the work that is done under the sun was grievous to me. For everything is futile and a pursuit of the wind.

18 I hated all for which I had toiled under the sun, because I must leave it to the man who comes after me.

19 And who knows whether that man will be wise or foolish? Yet he will take over all the labor at which I have worked skillfully under the sun. This too is futile.

20 So my heart began to despair over all the labor that I had done under the sun.

21 When there is a man who has labored with wisdom, knowledge, and skill, and he must give his portion to a man who has not worked for it, this too is futile and a great evil.

22 For what does a man get for all the toil and striving with which he labors under the sun?

23 Indeed, all his days are filled with grief, and his task is sorrowful; even at night, his mind does not rest. This too is futile.
