There is a story in the Bible about ten virgins -- the five wise virgins and the five foolish. It was said that the bridegroom was to come, and they were to light their lamps; and five were in time, and brought the oil, and lighted their lamps; and the other five waited until the bridegroom came, and when the bridegroom came, then they went to the five who had lighted their lamps and asked of them oil, and were refused.
