Proverbs 10:18-21

He who hides hatred has lying lips, And he who spreads slander is a fool. [Prov 26:24-26] When there are many words, transgression and offense are unavoidable, But he who controls his lips and keeps thoughtful silence is wise. The tongue of the righteous is like precious silver (greatly valued); The heart of the wicked is worth little. The lips of the righteous feed and guide many, But fools [who reject God and His wisdom] die for lack of understanding.
