In Context

18 I said in my heart concerning the sons of men, that God would prove them, and shew them to be like beasts.

19 Therefore the death of man, and of beasts is one, and the condition of them both is equal: as man dieth, so they also die: all things breathe alike, and man hath nothing more than beast: all things are subject to vanity.

20 And all things go to one place: of earth they were made, and into earth they return together.

21 Who knoweth if the spirit of the children of Adam ascend upward, and if the spirit of the beasts descend downward?

22 And I have found that nothing is better than for a man to rejoice in his work, and that this is his portion. For who shall bring him to know the things that shall be after him?
