"From whence they can no more return"

1. Mosiah 3: 25
   25 And if they be evil they are consigned to an awful view of their own guilt and abominations, which doth cause them to shrink from the presence of the Lord into a state of misery and endless torment, from whence they can no more return; therefore they have drunk damnation to their own souls.
2. 3 Ne. 27: 17
   17 And he that endureth not unto the end, the same is he that is also hewn down and cast into the fire, from whence they can no more return, because of the justice of the Father.
