Revelations 11(This occurs prior to the 7th trumpet.)
1 And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.
2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
3 And Iwill give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
4 These are the two olive trees, and the two candlesticks standing before the God of the earth.
5 And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.
6 These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.
A whole lot of things are going to change when the Messiah of Israel comes again.
For example ... I hope people here realize that the US Constitution will be scrapped, too. The Bill of Rights will be thrown into the trashcan. The right to own and have guns will be eliminated. And all those Ron Paul types also better realize that there won’t be any of these illegal drugs allowed that they all seem to want to legalize for the good of society.
There will be NO DUE PROCESS, no rights to an attorney and no right to a jury trial!
There’s gonna be a whole lot of other things that will change on this earth when the Messiah of Israel rules with a “rod of iron”!
BUT ... in terms of the Third Temple being built and your reference in Revelation, from what I have read (there in the Bible and elsewhere) the indications to me are that the Dome of the Rock stays and the Third Temple is built to north or to the south of it. I think it’s to the north, in front of the Golden Gate.
