Proverbs 10:18-21

He that hideth hatred is of lying lips; And he that uttereth a slander is a fool. In the multitude of words there wanteth not transgression; But he that refraineth his lips doeth wisely. The tongue of the righteous is as choice silver: The heart of the wicked is little worth. The lips of the righteous feed many; But the foolish die for lack of understanding.
