Ecclesiastes 3:10
9. What profit hath he that worketh in that wherein he laboureth?10. I have seen the travail, which God hath given to the sons of men to be exercised in it.11. He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.
