Ecclesiastes 3:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ For the fate of humans and the fate of animals is the same; as one dies, so dies the other. They all have the same breath, and humans have no advantage over the animals; for all is vanity. ²⁰ All go to one place; all are from the dust, and all turn to dust again. ²¹ Who knows whether the human spirit goes upwards and the spirit of animals goes downwards to the earth?
