2 Samuel 13:30

Which was not improbable, when the sword was once drawn among them, and one of them killed, which might provoke the rest to draw their swords, both to defend themselves, and to revenge their brother's death, and thereby occasion the death of all. And God suffered this false report to be spread for David's greater terror and humiliation, that he who had formerly rejoiced in the tidings of Uriah's death, might now be tormented with the report of the death of all his sons.
