I know I've mentioned this before, but I think this is a worthwhile thread on its own. I believe it may be possible that the Center of Temple Studies in Mitzpe Yericho is, in fact, the Third Temple itself.
I have four reasons for thinking this a possibility:
1.) In the video of its construction here http://www.newsofhisland.com/blog/?p=4499, a Rabbi at the construction site says, and I quote, "it will be an exact replica of the temple." Another Rabbi says, I quote, "it is the beginning of the work of the third temple, construction for the third temple."
2.) Revelation 11:1-2, which discusses the third temple has usually been interpreted as meaning "the court outside the sanctuary leave out", but this appears to be an NIV translation. The Greek and the King James seems to say "the court WITHOUT the sanctuary leave out". In other words, it may be plainly saying that the temple will not be built on the temple mount at all.
"And there was given to me a reed like to a rod, and the messenger stood, saying, `Rise, and measure the sanctuary of God, and the altar, and those worshipping in it;
and the court that is without the sanctuary leave out, and thou mayest not measure it, because it was given to the nations, and the holy city they shall tread down forty-two months;" - Revelation 11:1-2, YLT
3.) The timing of its construction seems to fit with the ENP(i) theory.
4.) The temple "replica" will specifically be for training the Levitical priests in performing the sacrifices.
I really think we need to find out more about this, but I'm not sure where to begin. The project is affiliated with the Temple Institute, but this particular project doesn't have its own website (at least that I can find).
One way we can find out more is if someone would be willing to call the Center and ask about it, I found the phone number of the project: 052-3003293
If anyone can call Israel and/or speaks Hebrew, calling and asking about it could be well worth it. I'm pretty sure they speak English, though.
At 3:09 in the video some of the blueprints and architectural plans can be seen, but it is hard to make them out. From what I can see it does look like the real deal. Revelation 11 seems to say the temple mount is given over to the nations, so this would make good sense.
