Ecclesiastes 1:3; Ecclesiastes 2:19; Ecclesiastes 2:20; Ecclesiastes 2:21; Ecclesiastes 5:16; Ecclesiastes 5:18; Ecclesiastes 8:17

3 What advantage does man have in all his work Which he does under the sun?

19 And who knows whether he will be a wise man or a fool? Yet he will have control over all the fruit of my labor for which I have labored by acting wisely under the sun. This too is vanity.

20 Therefore I completely despaired of all the fruit of my labor for which I had labored under the sun.

21 When there is a man who has labored with wisdom, knowledge and skill, then he gives his legacy to one who has not labored with them. This too is vanity and a great evil.

16 This also is a grievous evil -exactly as a man is born, thus will he die. So what is the advantage to him who toils for the wind?

18 Here is what I have seen to be good and fitting: to eat, to drink and enjoy oneself in all one's labor in which he toils under the sun during the few years of his life which God has given him; for this is his reward.

17 and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, "I know," he cannot discover.
