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. Let us not therefore be afraid of evil tidings, while they want confirmation, but, when we hear the worst, hope the best, at least hope better.
