יחזקאל, פרק מ״ד, פסוק ב׳

The permanent sealing of a specific gate in the Temple serves as a powerful symbol of exclusive holiness and the eternal presence of God. This architectural feature is not merely a matter of building design, but a profound spiritual statement about God entering His permanent dwelling. Because the prophecy focuses directly on the physical structure of the Temple and its gates [רד״ק], understanding the exact identity of this locked entrance and the reason for its closure reveals deep insights about the future sanctuary.

There are varying perspectives on exactly which gate is permanently shut. A straightforward understanding points to the main gate of the Sanctuary itself [רד״ק]. However, the Sages identify it as a smaller southern doorway. Alongside the great gate of the Sanctuary stood two smaller entrances, one to the north and one to the south. According to this tradition, no human has ever walked through the southern entrance, perfectly fulfilling the prophetic vision [רש״י, רד״ק]. A different approach suggests the locked entrance is the eastern gate of the outer courtyard. While the eastern gate of the inner courtyard operates on a schedule—closed on regular weekdays but open on Sabbaths and holidays—this outer gate remains permanently sealed. No person will ever be permitted to open it or even step into its inner space [מלבי״ם, ביאור שטיינזלץ].

The underlying reason for this permanent closure is that the God of Israel has entered through it. The primary approach among commentators is that God's glory passes through this specific route to enter the Temple [רד״ק, ביאור שטיינזלץ], a momentous event destined to occur in the future [רש״י]. Keeping the entrance locked carries two distinct meanings. First, it is a matter of deep reverence. Because God Himself used this pathway, it is considered inappropriate for any human to walk the same route, requiring the door to remain shut [מצודת דוד]. Second, the locked gate guarantees the eternal nature of the Third Temple. Sealing the entrance after God enters signifies that His presence will never depart from the sanctuary again. The gate is locked to ensure that His glory remains in that place forever [מלבי״ם].
