Uri Ariel of the National Union party in the Israeli Knesset is preparing plans to build a Jewish synagogue on the Temple Mount, with permission of the Jordanian Islamic Waqf and the Sanhedrin. Currently no Jew or Christian is permitted to wear religious symbols, carry Bibles or even pray on the Temple Mount, for fear of inciting the wrath of the Islamic Waqf who administer the mount. Observant Jews have pointed out that these restrictions were never decreed by the Israeli courts, and are an unwritten rule imposed by the Israeli police. The Temple Mount Faithful group, who regularly organize marches around the site in support of opening it up for Jewish worship, have on numerous occasions attempted to lay the cornerstone of the Third Temple, without success. The Jewish Sanhedrin, formed a few years ago after over 1600 years of diaspora, have also announced plans to investigate the exact site on which Herod's Temple stood, in preparation for the rebuilding of the Third Temple. The exact site has been disputed by Jewish scholars, but it is believed could be constructed without removing the mosque.

Quote: "The synagogue would be build upon the Temple Mount, but in an area that is indisputably not within the areas that require immersion and other preparations, according to Jewish law. Ariel says that the synagogue would not change the Muslim status quo on the mount, which is home to the Al-Aksa Mosque and the Dome of the Rock. �This is not a new idea,� Ariel stressed, �it has been brought up and considered countless times since the [1967] Six Day War [during which the Temple Mount was liberated from Jordanian occupation �ed.].� The plan will be submitted to the Jerusalem municipality and the Committee for Design and Construction for approval. Ariel says that every aspect of the plan will be submitted to leading Torah scholars for approval.

Because the synagogue will not be built, God willing, on ground on which the Temple once stood, and therefore would not require cleansing by the priests, animals sacrifices could not be carried out. In order for the Temple Mount to be cleansed, a pure red heifer (Numbers 19) needs to be sacrificed. A red heifer was born in Israel a few years ago, but was discovered to have imperfections, namely white hairs in her tail. Once a heifer of suitable quality is born and sacrificed, the Temple Mount can be cleansed and the sacrifices can be resumed. This coming Temple will of course be the one that the Antichrist subsequently defiles in the middle of the 7 year tribulation period. 

Jewish scholars have long wondered why, according to Numbers 19, that the man who sacrifices the red heifer, which is used to cleanse those who are defiled, becomes defiled himself in the slaying of the animal. This reminds us of our Lord Jesus Christ, who in His sacrifice upon the cross, was made sin for us. Not that Christ became defiled, but that He bore our defilement in His own body on the tree.

2nd Corinthians 5:21 
For He (God the Father) hath made Him (Jesus Christ) to be sin for us, Who knew no sin; that we might be made the righteousness of God in Him.
