Ecclesiastes 10:1

10:1 One dead fly makes the perfumer’s ointment give off a rancid stench,

so a little folly can outweigh much wisdom.

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.
