דברי הימים ב, פרק ג׳, פסוק ט׳

The profound investment in the Temple's construction is evident in its smallest details and highest levels, as even the minor connecting pieces and the upper floors were crafted from pure gold. To secure the gold plating to the wooden walls of the structure, specialized gold nails were used [רש"י, מצודת דוד]. Alternatively, these nails served a different purpose: anchoring thick gold plates directly to the Temple's stone floor, as the bare stones could not be plated in the usual manner [מלבי"ם]. The scale of this wealth is reflected in the weight of the fasteners, which stood at fifty shekels [רש"י, ביאור שטיינזלץ]. This measurement may have been even more astounding, representing the heavy weight of every individual nail [מלבי"ם].

Beyond the main halls, the walls of the upper levels of the building were also covered in gold [מצודת דוד]. These upper chambers rested directly above the Holy Sanctuary and the Holy of Holies, spanning a height of about ten cubits from the top of the main structure to the ceiling of the roof [רלב"ג]. This golden covering might have been reserved strictly for the chambers situated directly over the Holy of Holies, or it may have extended to every upper room throughout the entire Temple complex [מלבי"ם].

The specific inclusion of these golden elements—the exact weight of the nails and the plating of the upper chambers—provides a unique historical record. This information was entirely new, added by Ezra the Scribe in the Book of Chronicles, and does not appear in the parallel historical account found in the Book of Kings [מלבי"ם].
