2 Samuel 13:18-19
13:18 (Now she was wearing a long robe, for this is what the king’s virgin daughters used to wear.) So Amnon’s attendant removed her and bolted the door behind her.
13:19 Then Tamar put ashes on her head and tore the long robe she was wearing. She put her hands on her head and went on her way, wailing as she went.
