Proverbs 14:7

5 A faithful witness will not lie: but a false witness will utter lies.

6 A scorner seeketh wisdom, and findeth it not: but knowledge is easy unto him that understandeth.

Go from the presence of a foolish man, when thou perceivest not in him the lips of knowledge.

8 The wisdom of the prudent is to understand his way: but the folly of fools is deceit.

9 Fools make a mock at sin: but among the righteous there is favour.

Do read the surrounding verses too, because the context often says more than a single verse.
