14 There is a vanity that takes place on the earth that there are righteous men who are treated according to the deeds of the wicked, and there are wicked men who are treated according to the deeds of the righteous. I said that this also is vanity.
15 And I commend joy, for man has nothing better under the sun than to eat and drink and be joyful; for this will go with him in his labor all the days of his life that God has given him under the sun.
16 When I set my heart to know wisdom and to experience the affairs that are done on earth, though day and night there is no sleep for one’s eyes,
17 then I saw all the work of God, that a man cannot comprehend the work that is done under the sun. Inasmuch as a man labors to seek, he will not understand. Even if a wise man claims to know, he cannot grasp it.
