Proverbs 10:19-22, 31-32

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. The blessing of Jehovah, it maketh rich; And he addeth no sorrow therewith.

The mouth of the righteous bringeth forth wisdom; But the perverse tongue shall be cut off. The lips of the righteous know what is acceptable; But the mouth of the wicked speaketh perverseness.
