Ecclesiastes 3:9

9 What do workers gain from their toil?

Ecclesiastes 7:2

2 It is better to go to a house of mourning than to go to a house of feasting, for death is the destiny of everyone; the living should take this to heart.

Ecclesiastes 8:17

17 then I saw all that God has done. No one can comprehend what goes on under the sun. Despite all their efforts to search it out, no one can discover its meaning. Even if the wise claim they know, they cannot really comprehend it.

Ecclesiastes 9:2

2 All share a common destiny—the righteous and the wicked, the good and the bad, the clean and the unclean, those who offer sacrifices and those who do not. As it is with the good, so with the sinful; as it is with those who take oaths, so with those who are afraid to take them.
