“He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.”
Proverbs 17:27 (KJV)
Context Reading
25A foolish son is a grief to his father, and bitterness to her that bare him. 26Also to punish the just is not good, nor to strike princes for equity. 27He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit. 28Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.
