Proverbs 17:26-28 New American Standard Bible (NASB)

26. It is also not good to fine the righteous, Nor to strike the noble for their uprightness.

27. He who restrains his words has knowledge, And he who has a cool spirit is a man of understanding.

28. Even a fool, when he keeps silent, is considered wise; When he closes his lips, he is considered prudent.
