Ecclesiastes 3:19-21

Young's Literal Translation

¹⁹ For an event [is to] the sons of man, and an event [is to] the beasts, even one event [is] to them; as the death of this, so [is] the death of that; and one spirit [is] to all, and the advantage of man above the beast is nothing, for the whole [is] vanity.

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

²¹ Who 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?
