2 Samuel 13:19-23
English Standard Version
20And 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.
21When King David heard of all these things, he was very angry.
22But Absalom spoke to Amnon neither good nor bad, for Absalom hated Amnon, because he had violated his sister Tamar.
