The architecture of the Temple gates reflects a precise design that blends practical lighting solutions with deep spiritual meaning and beauty. Special windows were built into the walls of the chambers [מצודת ציון]. Because a window by definition cannot be completely blocked [רד״ק, אברבנאל], the exact nature of their sealed design is understood in a few different ways. The primary approach among commentators is that they were constructed on a slant, narrow on the inside and wide on the outside. This specific shape optimally distributed light and carried a spiritual message, showing that the Temple radiates light out to the world rather than needing light from the outside [רש״י, רד״ק, אברבנאל].
Another perspective suggests the windows were covered with a clear, pure material, similar to glass. This allowed light to enter while keeping out the wind and preventing outsiders from looking in [מלבי״ם, מצודת דוד, אברבנאל]. A third view proposes that the windows were crafted as narrow slits and lattices, much like shutters, allowing people inside to look out without being seen [אברבנאל].
These windows were set directly into the pillars and doorposts of the chambers, facing the inner space of the gate [רש״י, רד״ק, מצודת דוד, אברבנאל, ביאור שטיינזלץ]. This architectural pattern repeated throughout the structure, including the halls of the gates [רש״י, מצודת ציון]. The commentators agree that all these windows were directed inward toward the courtyard and inner spaces, rather than facing the outer wall, serving to illuminate the interior of the Temple [רש״י, רד״ק, אברבנאל].
To complete the design, the structure was adorned with impressive carvings. The top of every pillar and doorpost featured a sculpted capital shaped like a palm tree. This elegant detail was specifically chosen to add beauty and glory to the entire building [רש״י, רד״ק, מצודת דוד, אברבנאל, מלבי״ם, ביאור שטיינזלץ].
