2 Samuel 13:28-37

Now 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. And 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. And 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. Then the king arose, and tare his garments, and lay on the earth; and all his servants stood by with their clothes rent. And 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. Now therefore let not my lord the king take the thing to his heart, to think that all the king's sons are dead: for Amnon only is dead. But Absalom fled. And the young man that kept the watch lifted up his eyes, and looked, and, behold, there came much people by the way of the hill side behind him. And Jonadab said unto the king, Behold, the king's sons come: as thy servant said, so it is. And it came to pass, as soon as he had made an end of speaking, that, behold, the king's sons came, and lifted up their voice and wept: and the king also and all his servants wept very sore. But Absalom fled, and went to Talmai, the son of Ammihud, king of Geshur. And David mourned for his son every day.
