דברי הימים ב, פרק ד׳, פסוק י״ב

The magnificent copper craftsmanship prepared for the Temple featured two massive central columns created through a special casting process [ביאור שטיינזלץ]. The top of these pillars held a complex decorative structure, carefully detailed in the summary of the Temple's vessels.

At the head of the pillars sat capitals and bowls. Rather than being two completely separate items, they functioned together as the bowls of the capitals [מצודת דוד, מלבי״ם]. The lower section of each capital was crafted into a spherical shape, forming a base that resembled a large cup or bowl [ביאור שטיינזלץ, מצודת ציון].

Resting above these bowl-shaped bases was a layer of netting that formed the upper portion of the capital [ביאור שטיינזלץ, מצודת ציון]. This netting served a specific purpose: it covered the empty space inside the capital, from which decorative branches resembling palm fronds extended [רש״י]. Furthermore, earlier accounts of the Temple's construction mention chains that are absent from this particular summary. Because of this omission, some commentators identify this intricate netting as those very chains [רש״י].
