2 Samuel 13:20-22

And Absalom her brother said unto her, Hath Amnon thy brother been with thee? but hold now thy peace, my sister: he is thy brother; regard not this thing. So Tamar remained desolate in her brother Absalom's house. But when king David heard of all these things, he was very wroth. And Absalom spake unto his brother Amnon neither good nor bad: for Absalom hated Amnon, because he had forced his sister Tamar.
