The story of the wise virgins

Matthew 25
25:1 "Then the kingdom of heaven shall be likened to ten virgins who took their lamps and went out to meet the bridegroom.
25:2 Now five of them were wise, and five were foolish.
25:3 Those who were foolish took their lamps and took no oil with them,
25:4 but the wise took oil in their vessels with their lamps.
25:5 But while the bridegroom was delayed, they all slumbered and slept.
25:6 And at midnight a cry was heard: 'Behold, the bridegroom is coming; go out to meet him!'
25:7 Then all those virgins arose and trimmed their lamps.
25:8 And the foolish said to the wise, 'Give us some of your oil, for our lamps are going out.'
25:9 But the wise answered, saying, 'No, lest there should not be enough for us and you; but go rather to those who sell, and buy for yourselves.'
25:10 And while they went to buy, the bridegroom came, and those who were ready went in with him to the wedding; and the door was shut.
25:11 Afterward the other virgins came also, saying, 'Lord, Lord, open to us!'
25:12 But he answered and said, 'Assuredly, I say to you, I do not know you.'
25:13 Watch therefore, for you know neither the day nor the hour in which the Son of Man is coming.
