Proverbs 10:19-22, 31-32

In the multitude of words sin is not lacking, But he who restrains his lips is wise. The tongue of the righteous is choice silver; The heart of the wicked is worth little. The lips of the righteous feed many, But fools die for lack of wisdom. The blessing of the LORD makes one rich, And He adds no sorrow with it.

The mouth of the righteous brings forth wisdom, But the perverse tongue will be cut out. The lips of the righteous know what is acceptable, But the mouth of the wicked what is perverse.
