'Oil' in the Bible

And they were expelling many demons and anointing many sick [people] with olive oil and healing [them].

And [while] he was at Bethany in the house of Simon the leper, [as] he was reclining for a meal, a woman came holding an alabaster flask of very costly perfumed oil of genuine nard. [After] breaking the alabaster flask, she poured [it] out on his head.

But some were expressing indignation to one another: "Why has there been this waste of perfumed oil?

For this perfumed oil could have been sold for more than three hundred denarii and given to the poor!" And they began to scold her.
