1:15 That which is crooked cannot be made straight: and that which is wanting cannot be numbered.
1:16 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.
1:17 And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.
1:18 For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
