'Oil' in the Bible

But when you fast, put oil on your head and wash your face,

"At that time, the kingdom from heaven will be comparable to ten bridesmaids who took their oil lamps and went out to meet the groom.

because when the foolish ones took their lamps, they didn't take any oil with them.

But the wise ones took flasks of oil with their lamps.

"But the foolish ones told the wise, "Give us some of your oil, because our lamps are going out!'
