2 Samuel 13:32-35

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 has been determined from the day that he humbled his sister Tamar.

33And now let not my lord the king take the thing to heart, to say, All the king's sons are dead; for Amnon only is dead.

34And Absalom fled. And the young man that watched lifted up his eyes and looked, and behold, there came much people from the way behind him, from the hill-side.

35And Jonadab said to the king, Behold, the king's sons come: as thy servant said, so it is.
