Proverbs Concerning The Mouth

¹⁹
When there are many words, transgression and offense are unavoidable,
But he who controls his lips and keeps thoughtful silence is wise.
²⁰ 
The tongue of the righteous is like precious silver (greatly valued);
The heart of the wicked is worth little.
²¹
The lips of the righteous feed and guide many,
But fools [who reject God and His wisdom] die for lack of understanding.
