Ecclesiastes 2:17-22

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

18I hated all my work that I labored at under the sun because I must leave it to the one who comes after me.

19And who knows whether he will be wise or a fool? Yet he will take over all my work that I labored at skillfully under the sun. This too is futile.

20So I began to give myself over to despair concerning all my work that I had labored at under the sun.

21When there is a person whose work was done with wisdom, knowledge, and skill, and he must give his portion to a person who has not worked for it, this too is futile and a great wrong.

22For what does a person get with all his work and all his efforts that he labors at under the sun?
