Ecclesiastes 3:20-22

²⁰Every thing goeth unto one place: every thing came from the dust, and every thing returneth to the dust.

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

²²And so did I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion; for who can bring him to look with pleasure on what will be after him?
