Bringing the Ark of the Covenant into its permanent home marks the peak moment of the Temple's dedication. It is the exact moment when holiness finds its deepest and most internal resting place. The entry into the sacred space is a gradual, step-by-step process leading to the very center. This physical journey reflects a process of spiritual elevation, where the relationship between the Ark and the entire Temple is compared to the relationship between the soul and the human body [מלבי״ם]. Each stage of the Ark's placement mirrors a different state of the soul. Bringing it to the doorway of the inner sanctuary symbolizes the soul's light breaking outward to illuminate the body. Moving it deeper into the Holy of Holies corresponds to the soul residing within the mind, confined inside the physical form. Finally, placing the Ark under the wings of the Cherubim represents the highest spiritual level, which is the soul as it exists purely on its own in its heavenly, divine dwelling.
Regarding the final physical placement of the Ark, the primary approach among commentators is that the sheltering wings do not belong to the original Cherubim crafted by Moses in the desert [רש״י, רד״ק, מצודת דוד וביאור שטיינזלץ]. Those original figures were small and permanently attached to the Ark's cover. Instead, the Ark was brought beneath new, massive Cherubim built by King Solomon. These towering figures stood directly on the floor of the inner sanctuary, reaching five cubits high. They faced outward toward the main hall, with their great wings stretching completely from one wall to the other. The priests carefully guided the Ark between these two large figures, allowing it to rest safely under their vast, spread wings.
This detail explains why Solomon created new, different Cherubim for the Temple while keeping the original Ark exactly as it was. The decision to forge these new figures, along with the other new vessels and altars, was not driven by personal preference or architectural design. Rather, it was executed precisely according to a prophetic vision and a divine blueprint. This detailed plan was handed down in writing directly from God, passed to Solomon through his father, David [רד״ק].
