Proverbs 12:18-20

Amplified Bible

¹⁸ 
There is one who speaks rashly like the thrusts of a sword,
But the tongue of the wise brings healing.
¹⁹ 
Truthful lips will be established forever,
But a lying tongue is [credited] only for a moment.
²⁰ 
Deceit is in the heart of those who devise evil,
But counselors of peace have joy.
