Ecclesiastes 1:17

And I gave my heart to seek and explore by wisdom concerning all that has been done under heaven. It is a grievous endeavor which God has given to the sons of men with which to occupy themselves.

So I turned to see wisdom, madness, and simpleminded folly. What will the man do who will come after the king except what has already been done?

I turned my heart to know, to explore, and to seek wisdom and an explanation, and to know the wickedness of foolishness and the simpleminded folly of madness.

This is an evil in all that is done under the sun, that there is one fate for all. Furthermore, the hearts of the sons of men are full of evil, and madness is in their hearts throughout their lives. Afterwards they go to the dead.
