Matthew 25:1, 3-10

Then shall the kingdom of heaven be likened unto ten virgins, who took their lamps, and went forth to meet the bridegroom.

For the foolish, when they took their lamps, took no oil with them: but the wise took oil in their vessels with their lamps. Now while the bridegroom tarried, they all slumbered and slept. But at midnight there is a cry, Behold, the bridegroom! Come ye forth to meet him. Then all those virgins arose, and trimmed their lamps. And the foolish said unto the wise, Give us of your oil; for our lamps are going out. But the wise answered, saying, Peradventure there will not be enough for us and you: go ye rather to them that sell, and buy for yourselves. And while they went away to buy, the bridegroom came; and they that were ready went in with him to the marriage feast: and the door was shut.
