They basically claim a large army will gather to attack Israel and the Jews will hide in Petra and then God will send down fire and or a biological eye & face melting plague to kill all the countries in the world that attack Israel
Then Jesus will appear to them and they will accept Jesus
They base this on misunderstanding
Romans 9
Zechariah 12
Ezekiel 38
I do not believe this but this is my understanding of what I heard them say
Whether or not the Bible is true they are wrong
