Mt 25:10-13
While they went off to buy it, the bridegroom came and those who were ready went into the wedding feast with him. Then the door was locked. Afterwards the other virgins came and said, 'Lord, Lord, open the door for us!' But he said in reply, 'Amen, I say to you, I do not know you.' Therefore, stay awake, for you know neither the day nor the hour.
