The lighting system of the Tabernacle required more than just the main golden structure; it relied on a complete set of crafted tools and carefully prepared fuel. Expert artisans were tasked with preparing every component needed to maintain the light. This included the accessories necessary for cleaning and setting up the daily lighting, such as tongs and scoops [רש״י, ביאור שטיינזלץ]. Specialized bowls and cups were also crafted to rest on top of the structure, designed specifically to hold the wicks and the oil [רש״י, ביאור שטיינזלץ].
The inclusion of lighting oil alongside crafted metalwork presents an interesting detail, as oil is a combustible fuel rather than a manufactured tool. One view suggests that the oil is grouped with these items simply because the structure and its accessories were created specifically to serve it [אבן עזרא]. However, the primary approach among commentators is that preparing the oil was a highly skilled craft in its own right, requiring the expertise of specialized artisans.
This lighting fuel was not ordinary oil, but the result of a strict and unique extraction process. It required gathering olives specifically from the top of the tree to produce an exceptionally pure, pressed oil [רש״י, ריב״א, ביאור יש״ר, אבי עזר]. The crushing method used was not a routine task but a precise operation that guaranteed the highest possible level of purity and cleanliness [ברכת אשר על התורה].
Understanding the oil production as a specialized craft resolves its dual role in the construction of the Tabernacle. At an earlier stage, the oil was brought simply as a raw material, a willing donation from the generous people. Ultimately, however, it is treated as a finished masterpiece, transformed by the professional work of skilled craftsmen into the pure fuel needed for the light [ברכת אשר על התורה].
