Ecclesiastes 3:20-22 Modern English Version (MEV)
20 All go to one place: All are from the dust and all return to dust. 21 Who knows whether the spirit of man goes upward and the spirit of animals goes down to the earth?
22 So I saw that there is nothing better than that a man should rejoice in his labor, for that is his reward. For who will bring him to see what will happen after his life?
