2 Samuel 13:33-39

33 So now, let not my lord the king take this thing to heart, with the idea that all the king's sons are dead: for only Amnon is dead.
34 But Absalom went in flight. And the young man who kept the watch, lifting up his eyes, saw that a great band of people was coming down the slope by the way of the Horons; and the watchman came and gave word to the king, saying, I saw men coming down by the way of the Horons, from the hillside.
35 And Jonadab said to the king, See, the king's sons are coming; as your servant said, so it is.
36 And while he was talking, the king's sons came, with weeping and loud cries: and the king and all his servants were weeping bitterly.
37 So Absalom went in flight and came to Talmai, the son of Ammihud, the king of Geshur, where he was for three years.
38 And the king was sorrowing for his son all the time.
39 And the heart of David was wasted with desire for Absalom: for he was comforted for the death of Amnon.
