2 Samuel 13:18-22

Now she had on a long-sleeved garment; for this is how the virgin daughters of the king dressed themselves in robes. Then his attendant took her out and locked the door behind her.

Tamar took ashes and put them on her head, and tore her long-sleeved garment which was on her; and she put her hand on her head and went on her way, crying out as she went.

Then Absalom her brother said to her, “Has Amnon your brother been with you? But now keep silent, my sister, he is your brother; do not take this matter to heart.” So Tamar remained and was isolated in her brother Absalom’s house.

Now when King David heard about all these matters, he became very angry.

But Absalom did not speak with Amnon either good or bad; for Absalom hated Amnon because he had violated his sister Tamar.
