Ecclesiastes 3:20-22 English Standard Version (ESV)

20. All go to one place. All are from the dust, and to dust all return.

21. Who knows whether the spirit of man goes upward and the spirit of the beast goes down into the earth?

22. So I saw that there is nothing better than that a man should rejoice in his work, for that is his lot. Who can bring him to see what will be after him?
