Proverbs 10:19-22, 31-32

Sin is not ended by multiplying words, but the prudent hold their tongues. The tongue of the righteous is choice silver, but the heart of the wicked is of little value. The lips of the righteous nourish many, but fools die for lack of sense. The blessing of the LORD brings wealth, without painful toil for it.

From the mouth of the righteous comes the fruit of wisdom, but a perverse tongue will be silenced. The lips of the righteous know what finds favor, but the mouth of the wicked only what is perverse.
