2 Samuel 13:28-30

28Absalom commanded his servants, saying, “See now, 1when Amnon’s heart is merry with wine, and when I say to you, ‘Strike Amnon,’ then put him to death. Do not fear; have not I myself commanded you? Be courageous and be 2valiant.” 29The servants of Absalom did to Amnon just as Absalom had commanded. Then all the king’s sons arose and each mounted 3his mule and fled.

30Now it was while they were on the way that the report came to David, saying, “Absalom has struck down all the king’s sons, and not one of them is left.”
