Proverbs 14:28-30

Amplified Bible

²⁸ 
In a multitude of people is a king’s glory,
But in a lack of people is a [pretentious] prince’s ruin.
²⁹ 
He who is slow to anger has great understanding [and profits from his self-control],
But he who is quick-tempered exposes and exalts his foolishness [for all to see].^(A)
30 
A calm and peaceful and tranquil heart is life and health to the body,
But passion and envy are like rottenness to the bones.
