Ecclesiastes 2:19-22

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.

²¹Because there is a man whose work has been done with wisdom, with knowledge, and with an expert hand; but one who has done nothing for it will have it for his heritage. This again is to no purpose and a great evil.

²²What does a man get for all his work, and for the weight of care with which he has done his work under the sun?
