Matthew Henry on 2 Samuel 13:30–end
Here is, I. The fright that David was put into by a false report brought to Jerusalem that Absalom had slain all the king's sons, Sa2 13:30. It is common for fame to make bad worse; and the first news of such a thing as this represents it as more dreadful than afterwards it proves.
