When a wise man goes to court with a senseless man, there is raging and there is laughing, and no rest.
In context
7The righteous knows the cause of the poor; the wicked has no understanding to know it. 8Men of scoffing set a city ablaze, but the wise turn wrath away. 9When a wise man goes to court with a senseless man, there is raging and there is laughing, and no rest. 10Men of blood hate the blameless, and the upright seek his life. 11A fool lets out all his spirit, but a wise man holds it back and keeps it quiet.
