Proverbs 10:18-20

Amplified Bible

¹⁸ 
He who hides hatred has lying lips,
And he who spreads slander is a fool.^(A)
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.
