Proverbs 14:15

13 Even in laughter the heart is sorrowful; and the end of that mirth is heaviness.

14 The backslider in heart shall be filled with his own ways: and a good man shall be satisfied from himself.

The simple believeth every word: but the prudent man looketh well to his going.

16 A wise man feareth, and departeth from evil: but the fool rageth, and is confident.

17 He that is soon angry dealeth foolishly: and a man of wicked devices is hated.

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