Matthew 25:6-10

But at midnight there was a shout, ‘Look! The bridegroom [is coming]! Go out to meet him.’ Then all those virgins got up and put their own lamps in order [trimmed the wicks and added oil and lit them]. But the foolish virgins said to the wise, ‘Give us some of your oil, because our lamps are going out.’ But the wise replied, ‘No, otherwise there will not be enough for us and for you, too; go instead to the dealers and buy oil for yourselves.’ But while they were going away to buy oil, the bridegroom came, and those who were ready went in with him to the wedding feast; and the door was shut and locked.
