Ecclesiastes 3:21-22 American Standard Version (ASV)

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

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