Oil

In Benedict XVI's book set on Jesus, he mentioned that though water, bread, and wine were mentioned in John's gospel, there didn't seem to be anything referencing oil.

That did seem curious: oil was used for anointing, right? I hadn't noticed that before. I used the Gutenberg KJV to look.

Genesis has oil put on pillars to mark a place of worship. 2 references.

There are 11 uses of the word "oil" in reference to the temple lamps, and 55 for putting on the offerings. Note: two explicitly don't involve oil—the sin offering and the jealousy investigation offering.

39 are for some kind of anointing, 14 have to do with food, and 29 are kind of generic (produce of the land, etc). Perfume shows up once, as does oil for the skin and for general health. 3 times for healing, 2 times for use in other lamps, and 3 times the oil of gladness appears.

The only things that stand out to me are the exceptions to the oil on the offering. I don't think the jealousy offering has any significance to Jesus' mission (did the spouse commit adultery?). The sin offering, though…
