2 Samuel 13:30 KJV

28Now Absalom had commanded his servants, saying, Mark ye now when Amnon’s heart is merry with wine, and when I say unto you, Smite Amnon; then kill him, fear not: have not I commanded you? be courageous, and be valiant.

29And the servants of Absalom did unto Amnon as Absalom had commanded. Then all the king’s sons arose, and every man gat him up upon his mule, and fled.

30And it came to pass, while they were in the way, that tidings came to David, saying, Absalom hath slain all the king’s sons, and there is not one of them left.

31Then the king arose, and tare his garments, and lay on the earth; and all his servants stood by with their clothes rent.

32And Jonadab, the son of Shimeah David’s brother, answered and said, Let not my lord suppose that they have slain all the young men the king’s sons; for Amnon only is dead: for by the appointment of Absalom this hath been determined from the day that he forced his sister Tamar.
