Ecclesiastes 1:13; Ecclesiastes 1:16-18

Ecclesiastes 1:13

13 With all my heart I used wisdom to study and explore everything done under heaven. Mortals are weighed down with a terrible burden that God has placed on them.

Ecclesiastes 1:16-18

16 I thought to myself, "I have grown wiser than anyone who [has ruled] Jerusalem before me. I've had a lot of experience with wisdom and knowledge."

17 I've used my mind to understand wisdom and knowledge as well as madness and stupidity. [Now] I know that this is [like] trying to catch the wind.

18 With a lot of wisdom [comes] a lot of heartache. The greater [your] knowledge, the greater [your] pain.
