Then he led me to the gate, the gate facing east. And behold, the glory of the God of Israel was coming from the east. And the sound of his coming was like the sound of many waters, and the earth shone with his glory. And the vision I saw was just like the vision that I had seen when he came to destroy the city, and just like the vision that I had seen by the Chebar canal. And I fell on my face. As the glory of the LORD entered the temple by the gate facing east, the Spirit lifted me up and brought me into the inner court; and behold, the glory of the LORD filled the temple.
(Ezekiel 43:1-5 ESV)
…the Lord Himself will enter through the east gate of the temple. Interestingly enough, when the Turks controlled Jerusalem they knew of this prophecy and to prevent it from happening they sealed up the east gate with bricks and placed a graveyard in front of this gate back in 1517 AD. But this of course is not going to stop the Messiah from coming and it seems that He will not be entering the third temple or the tribulation temple but this fourth temple or the millennial temple He will enter into it!
