שמן למאר OIL FOR THE LIGHT — “clear olive-oil … to make the flame ascend continually”).
Chizkuni
שמן למאור, “oil for lighting;” since it is not customary for a king to enter his palace until the palace is complete and its furnishings are in place, as well as the illumination having been lit, this is mentioned already here. The same oil was also used for anointing all the sacred vessels.
Da'at Zekenim
שמן למאור, “oil for light;” it is somewhat puzzling why this verse has been inserted here, seeing that the entire chapter deals with materials used for building the Tabernacle with the exception of this item, although the requirements for the Table in the Tabernacle have not been mentioned here, although that would have been appropriate, if the Torah had wished to mention the requirements of the menorah, the lampstand. Also the firewood for the altar should have been mentioned, and the animals that were needed to be offered on the altar. Why was only the oil singled out? It is possible to answer this by saying that seeing that the oils for anointing was also used to anoint all the furnishings in the Tabernacle before they could perform their function, this oil had multiple functions and was not only used for providing the raw material from which lighting was supplied for the Tabernacle which had no windows. The same is true of the incense. In a king’s palace, in our physical universe, before the King enters it with a view to take up his residence, different pleasant smelling spices are scattered to dissipate remnants of unpleasant odours that had accumulated during its construction. It is clear therefore that no less would be done when a structure housing the presence of the shechinah, presence of the Creator would be made ready for His occupancy. We find that indeed the presence of the Lord in the Tabernacle was made possible only through the presence of the incense, i.e. the fragrance released by it through burning it; this thought has been spelled out in Leviticus 16,13: וכסה ענן הקטורת, “and the cloud of incense is to envelop the Holy Ark,” as well as again in verse 2 of the same chapter: כי בענן אראה על הכפורת, “for I appear in the cloud upon the cover of the Ark.” Even though the oil of which the Torah speaks here is not required for physical illumination in the Tabernacle, it reflects the honour paid to the Holy Presence of the celestial presence in the midst of the Jewish people.
