Proverbs 10:11, 13, 19-21, 31-32
Proverbs 10:11 ASV
The mouth of the righteous is a fountain of life; But violence covereth the mouth of the wicked.
Proverbs 10:13 ASV
In the lips of him that hath discernment wisdom is found; But a rod is for the back of him that is void of understanding.
Proverbs 10:19-21 ASV
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.
Proverbs 10:31-32 ASV
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.
