Ecclesiastes 3:18-22 (King James Version)

 ¹⁸I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.

 ¹⁹For 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.

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

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

 ²²Wherefore I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion: for who shall bring him to see what shall be after him?
