Many Christians think or have been led to believe that Moses will be the other witness beside Elijah when the two will preach in the streets of Jerusalem to the people of the world remaining, but the Bible says it’s appointed unto man once to die (then the judgment), and Enoch (before Noah’s Flood) went to heaven without dying, as did Elijah, so logically they will be the two witnesses who will preach the final warning (prophesied in the book of the Revelation) that it’s time to repent or be lost forever, those two who will be killed for it but then will resurrect for all the world to see.
