Ecclesiastes 2:17-20

¹⁷So I was hating life, because everything under the sun was evil to me: all is to no purpose and desire for wind.

¹⁸Hate had I for all my work which I had done, because the man who comes after me will have its fruits.

¹⁹And who is to say if that man will be wise or foolish? But he will have power over all my work which I have done and in which I have been wise under the sun. This again is to no purpose.

²⁰So my mind was turned to grief for all the trouble I had taken and all my wisdom under the sun.
