Ecclesiastes 2:17-19

Webster_Strongs(i)
  17 H8130 [H8804] Therefore I hated H2416 life H4639 ; because the work H6213 [H8738] that is wrought H8121 under the sun H7451 is grievous H1892 to me: for all is vanity H7469 and vexation H7307 of spirit.
  18 H8130 [H8804] Yea, I hated H5999 all my labour H6001 which I had taken H8121 under the sun H3240 [H8686] : because I should leave H120 it to the man H310 that shall be after me.
  19 H3045 [H8802] And who knoweth H2450 whether he shall be a wise H5530 man or a fool H7980 [H8799] ? yet shall he have rule H5999 over all my labour H5998 [H8804] in which I have laboured H2449 [H8804] , and in which I have showed myself wise H8121 under the sun H1892 . This is also vanity.
