'Fools' in the Bible

Watch your step whenever you visit God's house, and come more ready to listen than to offer a fool's sacrifice, since fools never think they're doing evil.

When you make a promise to God, don't fail to keep it, since he isn't pleased with fools. Keep what you promise

For the wise person thinks carefully when in mourning, but fools focus their thoughts on pleasure.

It is better to listen to a wise person's rebuke than to listen to the praise of fools.

Never be in a hurry to become internally angry, since anger settles down in the lap of fools.

The softly spoken words of the wise are to be heard rather than the shouts of a ruler of fools.
