'Oil' in the Bible

And early in the morning Jacob took the stone which had been under his head, and put it up as a pillar and put oil on it.

I am the God of Beth-el, where you put oil on the pillar and took an oath to me: now then, come out of this land and go back to the country of your birth.

And Jacob put up a pillar in the place where he had been talking with God, and put a drink offering on it, and oil.
