The wealth and splendor of the royal court during the reign of King Solomon reached unprecedented heights, fundamentally changing the standard for luxury materials. While it was common practice among monarchs to drink from and use silver vessels [אברבנאל], Solomon broke from this tradition. Every drinking vessel and all the items in the House of the Forest of Lebanon were crafted exclusively from gold. This was a highly refined and pure metal, carefully melted in a crucible to remove every trace of impurity [מצודת ציון, ביאור שטיינזלץ].
The primary approach among commentators is that silver was completely absent from these royal items for practical and economic reasons. Because gold was so incredibly abundant during this period, silver completely lost its prestige. It was considered virtually worthless and insignificant in the eyes of the royal court [רש״י, מצודת דוד, רד״ק, מצודת ציון, ביאור שטיינזלץ].
Beyond the economic reality, there is a deeper conceptual layer to this exclusive use of gold. Solomon viewed his reign as an era of absolute perfection, a state likened to a full moon. In a spiritual sense, this peak of perfection is represented by gold. However, this perspective is met with subtle critique. A balanced reality always requires the continued flow of loving-kindness, a spiritual trait that is embodied precisely by silver [חומת אנך].
