The Permanent Closing of the East Gate of the Heavenly Temple (Ezekiel 44:1-3).
‘Then he brought me back the way of the outer gate of the sanctuary which looks towards the east, and it was shut. And Yahweh said to me, “This gate will be shut, it shall not be opened, neither shall any man enter by it, for Yahweh the God of Israel has entered in by it. Therefore it shall be shut.” '
Having heard the voice of the Lord Yahweh speaking to him from the sanctuary with instructions about the altar, Ezekiel was now brought by the heavenly visitant back to the east gate of the heavenly temple. And he found that it was permanently closed. For a similar abrupt reintroduction of the heavenly visitant see Ezekiel 46:19.
God then spoke to him again and told him the reason for the closure. It was because Yahweh, the God of Israel had Himself entered by it. Thus it was to remain shut up until it released the overflowing of blessing for which it was purposed (chapter 47).
This kind of ban was also known among earthly monarchs of great importance. When the great king had entered a city, the gate through which he entered would for a time be closed to common people because he had passed through it, in recognition of his status and greatness.
This was once again to remind God's people of His holiness. Once His glory had been in contact with something it was ‘very holy'. It could not be touched by common man. This was now true of the gate of the heavenly temple by which Yahweh had entered. His glory remained in it (compare Exodus 34:29). As far as we know the restriction was never placed on an earthly temple. Even though the glory of Yahweh did enter the second temple (Haggai 2:4-9 with 21-23), there is no mention of His entering by any gate or of an east gate ever having been shut permanently (although nor do we know that it was not. We do not know the make up of the second temple).
But this gate was no ordinary gate. It was a supernatural gate. For one day from under its threshold would flow rivers of living water, and such abundant waters that they would transform the landscape, and the world, and this too was measured by the man with the measuring line (Ezekiel 47:3). Thus the gate symbolised the unique presence of God waiting in heavenly power in His heavenly temple to burst forth on the world.
