Ecclesiastes 1:13-17

ASV_Strongs(i)
  13 H5414 And I applied H3820 my heart H1875 to seek H8446 and to search out H2451 by wisdom H6213 concerning all that is done H8064 under heaven: H7451 it is a sore H6045 travail H430 that God H5414 hath given H1121 to the sons H120 of men H6031 to be exercised therewith.
  14 H7200 I have seen H4639 all the works H6213 that are done H8121 under the sun; H1892 and, behold, all is vanity H7469 and a striving H7307 after wind.
  15 H5791 That which is crooked H3201 cannot H8626 be made straight; H2642 and that which is wanting H3201 cannot H4487 be numbered.
  16 H1696 I communed H3820 with mine own heart, H559 saying, H3254 Lo, I have gotten H1431 me great H2451 wisdom H6440 above all that were before H3389 me in Jerusalem; H3820 yea, my heart H7235 hath had great H7200 experience H2451 of wisdom H1847 and knowledge.
  17 H5414 And I applied H3820 my heart H3045 to know H2451 wisdom, H3045 and to know H1947 madness H5531 and folly: H3045 I perceived H1571 that this H7475 also was a striving H7307 after wind.
