What 3 1/2 years? The A of D IS the Dome of the Rock. See my last post on this thread. Two witnesses? Do you have any idea who the two witnesses are and support it Scripturally? I'd like to hear your take on this. Not what you think it is but rather what you know it is and back it up with some kind of evidence.
You need to read the entire book of Daniel, but mainly chapters 7-12.
