'Lamps' in the Bible

“Then the kingdom of heaven will be like 10 virgins who took their lamps and went out to meet the groom.

When the foolish took their lamps, they didn’t take olive oil with them.

But the sensible ones took oil in their flasks with their lamps.

“Then all those virgins got up and trimmed their lamps.

But the foolish ones said to the sensible ones, ‘Give us some of your oil, because our lamps are going out.’
