2 Samuel 13:20-23 New International Version (NIV)

20. Her brother Absalom said to her, “Has that Amnon, your brother, been with you? Be quiet for now, my sister; he is your brother. Don’t take this thing to heart.” And Tamar lived in her brother Absalom’s house, a desolate woman.

21. When King David heard all this, he was furious.

22. And Absalom never said a word to Amnon, either good or bad; he hated Amnon because he had disgraced his sister Tamar.

23. Two years later, when Absalom’s sheepshearers were at Baal Hazor near the border of Ephraim, he invited all the king’s sons to come there.
