2 Samuel 13:30-34

Now it happened while they were on the way [back home], that the [exaggerated] report came to David, “Absalom has killed all the king’s sons, and not one of them is left.” Then the king stood and tore his clothes and lay on the ground [in mourning]; and all his servants were standing by with their clothes torn. But Jonadab the son of Shimeah, David’s brother, responded, “Do not let my lord assume that all the king’s sons have been put to death; for only Amnon is dead. This act of revenge has been on Absalom’s mind since the day Amnon violated his sister Tamar. So now, do not let my lord the king take the report to heart that all the king’s sons are dead; for Amnon alone is dead.” Now Absalom fled. And the young man who kept watch looked up, and behold, many people were coming from the road behind him by the side of the mountain.
