'Virgins' in the Bible

“Then the kingdom of heaven will be comparable to ten virgins, who took their lamps and went out to meet the bridegroom.

Then all those virgins rose and trimmed their lamps.

Later the other virgins also came, saying, ‘Lord, lord, open up for us.’

Now concerning virgins I have no command of the Lord, but I give an opinion as one who by the mercy of the Lord is trustworthy.
