Ecclesiastes 3:19

3:19 For the fate of humans and the fate of animals are the same:

As one dies, so dies the other; both have the same breath.

There is no advantage for humans over animals,

for both are fleeting.

Ecclesiastes 6:12

6:12 For no one knows what is best for a person during his life –

during the few days of his fleeting life –

for they pass away like a shadow.

Nor can anyone tell him what the future will hold for him on earth.
