God has made everything fit beautifully ¹  in its appropriate time, but ²  he has also placed ignorance ³  in the human heart ⁴  so that ⁵  people ⁶  cannot discover what God has ordained, ⁷  from the beginning to the end ⁸  of their lives. ⁹ 

In times of prosperity ¹  be joyful, but in times of adversity ²  consider this: God has made one as well as the other, ³  so that no one can discover what the future holds. ⁴ 

then I discerned all that God has done: ¹  No one really comprehends what happens ²  on earth. ³  Despite all human ⁴  efforts to discover it, no one can ever grasp ⁵  it. ⁶  Even if ⁷  a wise person claimed ⁸  that he understood, he would not really comprehend ⁹  it.
