When King David passed the architectural plans for the Temple to his son Solomon, the instructions included precise measurements for the precious metals needed to craft the sacred vessels. Among these blueprints were the specific weights of gold and silver allocated for the various tables used in the daily service.
The plans required a set amount of gold for the tables dedicated to the Showbread. Rather than a single piece of furniture, the Sanctuary housed ten distinct golden tables upon which the sacred bread was arranged [רש״י, רלב״ג].
Alongside the golden tables, the blueprints provided silver for a different set of tables. The primary approach among commentators is that these silver tables were designed to assist with the practical work of the Temple [ביאור שטיינזלץ]. Placed in the Temple courtyard, they were specifically used for skinning the animal sacrifices [רש״י, מצודת דוד]. Even though these tables do not appear in the primary historical accounts of Solomon's construction, they are featured later in prophetic visions of the Temple, confirming their actual presence in the First Temple [מצודת דוד].
Alternatively, another perspective suggests that the silver tables had nothing to do with preparing sacrifices, but were instead directly connected to the Showbread ritual. According to this view, a silver table stood just outside the Sanctuary. When the priests came to arrange the fresh loaves, they would place the old, removed bread on this silver table [מלבי״ם].
