Ecclesiastes 1:16 in the World English Bible
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.”
Context
15 That which is crooked cannot be made straight: and that which is wanting cannot be numbered.
16 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.
17 And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.
