Think of the alarm that now seizes them when the tumult of rage gives way to the conviction of guilt. III. IT RECORDS WHAT THEY SAID. 1. What shall we do? This explanation is the utterance of concern — concern which it is not in the power of language to express. 2. It is the utterance of ingenuous confession. 3. It is the language of surrender.
