Ecclesiastes 3:9

⁷  A time to rend, and a time to sew; a time to keep silence, and a time to speak;

⁸  A time to love, and a time to hate; a time of war, and a time of peace.

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.
