3:9 What benefit can a worker ¹  gain from his toil? ² 

3:10 I have observed the burden

that God has given to people ³  to keep them occupied.

3:11 God has made everything fit beautifully ⁴  in its appropriate time,

but ⁵  he has also placed ignorance ⁶  in the human heart ⁷ 

so that ⁸  people ⁹  cannot discover what God has ordained, ¹⁰ 

from the beginning to the end ¹¹  of their lives. ¹²
