Ecclesiastes 3:19-21

King James Version

¹⁹ For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity.

²⁰ All go unto one place; all are of the dust, and all turn to dust again.

²¹ Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth?
