Samuel 13 describes Amnon becoming obsessed with Tamar and, following Jonadab's scheme, pretending illness so she would come prepare food for him privately. Despite Tamar's protests, Amnon raped her and then drove her away. She publicly mourned and lived desolate in Absalom's house.
David was angry, while Absalom concealed his hatred for Amnon for two years before arranging Amnon's murder.
