20 So I turned me to refrain my mind from all such travail, as I took under the Sun:
21 Forsomuch as a man should weary himself with wisdom, with understanding and opportunity, and yet be fain to leave his labours unto another, that never sweat for them. This is also a vain thing and a great misery.
22 For what getteth a man of all the labor and travail of his mind, that he taketh under the Sun,
23 but heaviness, sorrow and disquietness all the days of his life? Insomuch that his heart cannot rest in the night. Is not this also a vain thing?
