Also to punish the just is not good, nor to strike princes for equity.
Context
25 A foolish son brings grief to his father, and bitterness to her who bore him.
26 Also to punish the righteous is not good, nor to flog officials for their integrity.
27 He who spares his words has knowledge. He who is even tempered is a man of understanding.
