'Protest' in the Bible

They had no desire for my teaching, and my words of protest were as nothing to them.

A word of protest goes deeper into one who has sense than a hundred blows into a foolish man.

A judge is moved by one who for a long time undergoes wrongs without protest, and by a soft tongue even bone is broken.

Better is open protest than love kept secret.

He who says words of protest to a man will later have more approval than one who says smooth words with his tongue.
