3:10 I have observed the burden
that God has given to people to keep them occupied.
6:1 Here is another misfortune that I have seen on earth,
and it weighs heavily on people:
7:22 For you know in your own heart
that you also have cursed others many times.
10:5 I have seen another misfortune on the earth:
It is an error a ruler makes.
10:7 I have seen slaves on horseback
and princes walking on foot like slaves.
