2 Samuel 13:15–22
15 Then Amnon hated her with very great hatred, so that the hatred with which he hated her was greater than the love with which he had loved her. And Amnon said to her, “Get up! Go!” 16 But she said to him, “No, my brother, for this wrong in sending me away is greater than the other that you did to me.”2 But he would not listen to her. 17 He called the young man who served him and said, “Put this woman out of my presence and bolt the door after her.” 18 Now she was wearing ea long robe with sleeves, 3 for thus were the virgin daughters of the king dressed. So his servant put her out and bolted the door after her. 19 And Tamar fput ashes on her head and gtore the long robe that she wore. And hshe laid her hand on her head and went away, crying aloud as she went.
20 And her brother Absalom said to her, “Has Amnon your brother been with you? Now hold your peace, my sister. He is your brother; do not take this to heart.” So Tamar lived, a desolate woman, in her brother Absalom’s house. 21 When King David heard of all these things, he was very angry.4 22 But Absalom spoke to Amnon ineither good nor bad, for Absalom hated Amnon, because he had violated his sister Tamar.
