Ecclesiastes 1:16 in the King James Version
I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.
Context
15 That which is crooked can’t be made straight; and that which is lacking can’t be counted.
16 I said to myself, “Behold, I have obtained for myself great wisdom above all who were before me in Jerusalem. Yes, my heart has had great experience of wisdom and knowledge.”
17 I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.
