Ecclesiastes 3:19-21

LITV(i) 19 For that which happens to the sons of men, and that which happens to beasts, even one event is to them. As this one dies, so that one dies; yea, one breath is to all; so that there is to the man no advantage over the beast; for all is vanity. 20 All go to one place; all are of the dust, and all return to the dust. 21 Who knows the spirit of the sons of man, whether it goes upward; and the spirit of the beast, whether it goes downward to the earth?
