…are you seriously suggesting David Koresh, child molester and murderer, was King David reborn?
Anyway, I only bring up Koresh in the sense of what you said about how the world would treat someone claiming to be the Messiah.
Burning them out would be what I believe the corrupt governments of the world's response would be to anyone claiming to be the Messiah if people actually started to listen to them and believe in them as the Messiah.
Fore David is King forever and our corrupt governments would fall under his rule, yet they do not want to be ruled by David, or any other Godly person, they are corrupt.
Did Koreish rebuild Solomon's temple to God on the Temple Mount?
No, but then neither did King David build the original temple we call the first temple. Solomon did, David's son. God said the David was not holy enough to build it for what he did to Bathsheba's husband.
So only if one Koreish's living children rebuilds Soloman's Temple to God on the Temple Mount would I say Koreish was the actual Jewish Messiah.
I do not know if any of the four reported living children of Koreeish are men, or if that even matters, I only know that I believe it would be the Messiah ben David
to rebuild the Temple, because that is the way it happened the first time.
The Messiah ben David would also reincarnate the Messiah ben Joseph, and that in this sense would have to be Koreish himself.
However, in order for that to be so, Koreish's father , step father, or one of his father-in-laws would have had to be known as Joseph, because Koreish would literally have to be the Son of Joseph and as far as I know he was not.
