Ecclesiastes 1:13; Ecclesiastes 1:16-18

Ecclesiastes 1:13

13 And I applied my heart to seek out and examine by wisdom concerning all things that are done under heaven, for God has given to the sons of men an evil trouble to be troubled therewith.

Ecclesiastes 1:16-18

16 I spoke in my heart, saying, Behold, I am increased, and have acquired wisdom beyond all who were before me in Jerusalem: also I applied my heart to know wisdom and knowledge.

17 And my heart knew much—wisdom, and knowledge, parables and understanding: I perceived that this also is waywardness of spirit.

18 For in the abundance of wisdom is abundance of knowledge; and he that increases knowledge will increase sorrow.
