SC, are you speaking of the 2 Witnesses who come back in Revelation? This could be Moses, Elijah or Enoch.
Reincarnation I think is a trick of Satan, this gives people the false belief that even if they get it wrong in this life they will one day return to keep doing it all over again like life with a revolving door. Some even believe they will come back as an animal or even plant life. Does this seem like reality?
