Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.
… 
They that were foolish took their lamps, and took no oil with them:
But the wise took oil in their vessels with their lamps.
… 
Then all those virgins arose, and trimmed their lamps.
And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.
