Ecclesiastes 3:10-12

Young's Literal Translation

¹⁰ I have seen the travail that God hath given to the sons of man to be humbled by it.

¹¹ The whole He hath made beautiful in its season; also, that knowledge He hath put in their heart without which man findeth not out the work that God hath done from the beginning even unto the end.

¹² I have known that there is no good for them except to rejoice and to do good during their life,
