'Lamps' in the Bible

"Then the kingdom of heaven may be compared to ten virgins who took their lamps [and] went out to meet the bridegroom.

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.

Then all those virgins woke up and trimmed their lamps.

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

"{You must be prepared for action} and [your] lamps burning.

Now there were quite a few lamps in the upstairs room where we were gathered.
