Ecclesiastes 1:16; Ecclesiastes 2:4; Ecclesiastes 2:9

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.

4 I made me great works; I builded me houses; I planted me vineyards:

9 So I was great, and increased more than all that were before me in Jerusalem: also my wisdom remained with me.
