8:16 When I tried ¹  to gain ²  wisdom

and to observe the activity ³  on earth –

even though it prevents anyone from sleeping day or night ⁴  –

8:17 then I discerned all that God has done: ⁵ 

No one really comprehends what happens ⁶  on earth. ⁷ 

Despite all human ⁸  efforts to discover it, no one can ever grasp ⁹  it. ¹⁰ 

Even if ¹¹  a wise person claimed ¹²  that he understood,

he would not really comprehend ¹³  it. ¹⁴
