Ecclesiastes 8:15-17

Webster_Strongs(i)
  15 H7623 [H8765] Then I commended H8057 mirth H120 , because a man H2896 hath no better thing H8121 under the sun H398 [H8800] , than to eat H8354 [H8800] , and to drink H8055 [H8800] , and to be merry H3867 [H8799] : for that shall abide H5999 with him of his labour H3117 the days H2416 of his life H430 , which God H5414 [H8804] giveth H8121 him under the sun.
  16 H5414 [H8804] When I applied H3820 my heart H3045 [H8800] to know H2451 wisdom H7200 [H8800] , and to see H6045 the business H6213 [H8738] that is done H776 upon the earth H3117 : (for also there is that neither day H3915 nor night H7200 [H8802] seeth H8142 sleep H5869 with his eyes:)
  17 H7200 [H8804] Then I beheld H4639 all the work H430 of God H120 , that a man H3201 [H8799] cannot H4672 [H8800] find out H4639 the work H6213 [H8738] that is done H8121 under the sun H834 : because H7945 though H120 a man H5998 [H8799] may labour H1245 [H8763] to seek it out H4672 [H8799] , yet he shall not find H2450 it; yea further; though a wise H559 [H8799] man thinketh H3045 [H8800] to know H3201 [H8799] it, yet shall he not be able H4672 [H8800] to find it.
