13And I gavemy heartto seekand search outby wisdom concerning all things that are doneunder heaven: this soretravailhath Godgivento the sonsof manto be exercised therewith.
14I have seenall the worksthat are doneunder the sun; and, behold, all is vanityand vexationof spirit.
15That which is crookedcannotbe made straight: and that which is wantingcannotbe numbered.
16I communedwith mine own heart, saying, Lo, I am come to great estate, and have gottenmore wisdom than all they that have been beforeme in Jerusalem: yea, my hearthad greatexperienceof wisdomand knowledge.
17And I gavemy heartto knowwisdom, and to knowmadnessand folly: I perceivedthat thisalso is vexationof spirit.
18For in muchwisdom is muchgrief: and he that increasethknowledgeincreasethsorrow.
