2 Samuel 13:20-22

Her brother Absalom said to her, “Has your brother Amnon had his way with you? Now, my dear sister, let’s keep it quiet—a family matter. He is, after all, your brother. Don’t take this so hard.” Tamar lived in her brother Absalom’s home, bitter and desolate. King David heard the whole story and was enraged, but he didn’t discipline Amnon. David doted on him because he was his firstborn. Absalom quit speaking to Amnon—not a word, whether good or bad—because he hated him for violating his sister Tamar.
