II Samuel 13:20-22

And Absalom her brother said to her, “Has Amnon your brother been with you? But now hold your peace, my sister. He is your brother; do not take this thing to heart.” So Tamar remained desolate in her brother Absalom’s house. But when King David heard of all these things, he was very angry. And Absalom spoke to his brother Amnon neither good nor bad. For Absalom hated Amnon, because he had forced his sister Tamar.
