Ecclesiastes 8:7

7 Yet no one knows what will happen, because who can tell him what will happen?

Ecclesiastes 8:15

15 So I commended enjoyment, because there is nothing better for man under the sun except to eat, drink, and enjoy himself, for this will accompany him in his labor during the years of his days that God gives him under the sun.

Ecclesiastes 8:17

17 I observed all the work of God [and concluded] that man is unable to discover the work that is done under the sun. Even though a man labors hard to explore it, he cannot find it; even if the wise man claims to know it, he is unable to discover it.
