דברי הימים ב, פרק ט׳, פסוק כ׳

The immense wealth of King Solomon was most visibly reflected in the raw materials found throughout his royal court. Every single drinking vessel he owned was crafted from solid gold. This extraordinary standard of luxury extended to all the furnishings within his palace, famously known as the House of the Forest of Lebanon [רלב״ג].

The gold used for these items was not of ordinary quality. It was a highly refined, pure metal that had been sealed inside a refiner's crucible, a specialized process designed to burn away all impurities and waste [מצודת ציון, ביאור שטיינזלץ]. Because this flawless gold was so overwhelmingly abundant during Solomon's reign, silver completely lost its economic standing. In an era defined by such extreme prosperity, silver was entirely overshadowed and considered practically worthless [מצודת דוד, ביאור שטיינזלץ].
