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. However, this false news gave as much affliction to David, for the present, as if it had been true; he tore his garments, and lay on the earth, while as yet it was only a flying story, Sa2 13:31.

Virgil has given, in his best manner, a fine personification of Fame or Evil Report. - Aen. iv., 173.
Extemplo Libyae magnas it Fama per urbes;
Fama, malum qua non aliud velocius ullum,
Mobilitate viget, viresque adquirit eundo, etc.
"Now Fame, tremendous fiend! without delay,
Through Libyan cities took her rapid way;
Fame, the swift plague, that every moment grows,
And gains new strength and vigor as she goes," etc.
John Gill on 2 Samuel 13:31
Then the king arose, and tore his garments,.... In token of extreme grief and sorrow, as Jacob did when he was shown the coat of Joseph, supposing him to have been slain, as David thought all his sons were, Genesis 37:34,
and lay on the earth; on the bare ground, another token of mourning; so Job did on hearing the death of his sons, Job 1:20,
and all his servants stood by with their clothes rent: did as David did, in imitation of him, joining with him in expressions of sorrow; these were his courtiers, ministers of state, and principal officers in his household.
