'Oil' in the Bible

But [when] you are fasting, {put olive oil on your head} and wash your face

For [when] the foolish ones took their lamps, they did not take olive oil with them.

But the wise ones took olive oil in flasks with their lamps.

And the foolish ones said to the wise ones, 'Give us [some] of your olive oil, because our lamps are going out!'

But the wise ones answered saying, "Certainly there will never be enough for us and for you! Go instead to those who sell [olive oil] and buy [some] for yourselves.'

a woman came up to him holding an alabaster flask of very expensive perfumed oil, and poured [it] out on his head [while he] was reclining at table.
