Ecclesiastes 10:8–15
8 He who digs a pit will fall into it,
and a serpent will bite him who breaks through a wall.
9 He who quarries stones is hurt by them,
and he who splits logs is endangered by them.
10 If the iron is blunt, and one does not sharpen the edge,
he must use more strength,
but wisdom helps one to succeed.
11 If the serpent bites before it is charmed,
there is no advantage to the charmer.
12 The words of a wise man’s mouth win him favor,
but the lips of a fool consume him.
13 The beginning of the words of his mouth is foolishness,
and the end of his talk is evil madness.
14 A fool multiplies words,
though no man knows what is to be,
and who can tell him what will be after him?
15 The toil of a fool wearies him,
for he does not know the way to the city.

Matthew 25:1–13
The Parable of the Ten Virgins
25 “Then the kingdom of heaven will be like ten virgins who took their lamps and went to meet the bridegroom. 2 Five of them were foolish, and five were wise. 3 For when the foolish took their lamps, they took no oil with them, 4 but the wise took flasks of oil with their lamps. 5 As the bridegroom was delayed, they all became drowsy and slept. 6 But at midnight there was a cry, ‘Here is the bridegroom! Come out to meet him.’ 7 Then all those virgins rose and trimmed their lamps. 8 And the foolish said to the wise, ‘Give us some of your oil, for our lamps are going out.’ 9 But the wise answered, saying, ‘Since there will not be enough for us and for you, go rather to the dealers and buy for yourselves.’ 10 And while they were going to buy, the bridegroom came, and those who were ready went in with him to the marriage feast, and the door was shut. 11 Afterward the other virgins came also, saying, ‘Lord, lord, open to us.’ 12 But he answered, ‘Truly, I say to you, I do not know you.’ 13 Watch therefore, for you know neither the day nor the hour.
