Ecclesiastes 3:19-21 Holman Christian Standard Bible (HCSB)

19. For the fate of people and the fate of animals is the same. As one dies, so dies the other; they all have the same breath. People have no advantage over animals since everything is futile.

20. All are going to the same place; all come from dust, and all return to dust.

21. Who knows if the spirit of people rises upward and the spirit of animals goes downward to the earth?
