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.
18
For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
