Ecclesiastes 3:20-22

²⁰The whole are going unto one place, the whole have been from the dust, and the whole are turning back unto the dust.

²¹Who knoweth the spirit of the sons of man that is going up on high, and the spirit of the beast that is going down below to the earth?

²²And I have seen that there is nothing better than that man rejoice in his works, for it is his portion; for who doth bring him in to look on that which is after him?
