14 The wise man has eyes in his head, while the fool walks in the darkness; but I came to realize that the same fate overtakes them both. 15 Then I thought in my heart, "The fate of the fool will overtake me also. What then do I gain by being wise?" I said in my heart, "This too is meaningless." 16 For the wise man, like the fool, will not be long remembered; in days to come both will be forgotten. Like the fool, the wise man too must die!
5 The fool folds his hands and ruins himself.
13 Better a poor but wise youth than an old but foolish king who no longer knows how to take warning.
1 Guard your steps when you go to the house of God. Go near to listen rather than to offer the sacrifice of fools, who do not know that they do wrong.
3 As a dream comes when there are many cares, so the speech of a fool when there are many words. 4 When you make a vow to God, do not delay in fulfilling it. He has no pleasure in fools; fulfill your vow.
8 What advantage has a wise man over a fool? What does a poor man gain by knowing how to conduct himself before others?
4 The heart of the wise is in the house of mourning, but the heart of fools is in the house of pleasure. 5 It is better to heed a wise man's rebuke than to listen to the song of fools. 6 Like the crackling of thorns under the pot, so is the laughter of fools. This too is meaningless.
9 Do not be quickly provoked in your spirit, for anger resides in the lap of fools.
17 The quiet words of the wise are more to be heeded than the shouts of a ruler of fools.
2 The heart of the wise inclines to the right, but the heart of the fool to the left.
12 Words from a wise man's mouth are gracious, but a fool is consumed by his own lips.
15 A fool's work wearies him; he does not know the way to town.
