Proverbs 17:26
“Also to punish the just is not good, nor to strike princes for equity.”
Wisdom is before him that hath understanding; but the eyes of a fool are in the ends of the earth.
A foolish son is a grief to his father, and bitterness to her that bare him.
Also to punish the just is not good, nor to strike princes for equity.
He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.
Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.
