The King was much distressed; yet, on account of his oath and of the guests at his table, he did not like to refuse her.

While the prudent ones, besides taking their lamps, took oil in their jars. As the bridegroom was late in coming, they all became drowsy, and slept. But at midnight a shout was raised--'The Bridegroom is coming! Come out to meet him!' Then all the bridesmaids awoke and trimmed their lamps. And the foolish said to the prudent 'Give us some of your oil; our lamps are going out.' But the prudent ones answered 'No, for fear that there will not be enough for you and for us. Go instead to those who sell it, and buy for yourselves.' But while they were on their way to buy it, the bridegroom came; and the bridesmaids who were ready went in with him to the banquet, and the door was shut. Afterwards the other bridesmaids came. 'Sir, Sir,' they said, 'open the door to us!' But the bridegroom answered 'I tell you, I do not know you.' Therefore watch, since you know neither the Day nor the Hour.
