Proverbs 26:2-5 New International Version (NIV)

2. Like a fluttering sparrow or a darting swallow, an undeserved curse does not come to rest.

3. A whip for the horse, a bridle for the donkey, and a rod for the backs of fools!

4. Do not answer a fool according to his folly, or you yourself will be just like him.

5. Answer a fool according to his folly, or he will be wise in his own eyes.
