2 Samuel 13:20-22

20Her 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. 21When King David heard all this, he was furious.

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