Proverbs 10:19-22, 31-32

Too much talk leads to sin. Be sensible and keep your mouth shut. The words of the godly are like sterling silver; the heart of a fool is worthless. The words of the godly encourage many, but fools are destroyed by their lack of common sense. The blessing of the LORD makes a person rich, and he adds no sorrow with it.

The mouth of the godly person gives wise advice, but the tongue that deceives will be cut off. The lips of the godly speak helpful words, but the mouth of the wicked speaks perverse words.
