What does 2 Samuel 13:8 mean?

Jonadab said, 'Here's what you should do: Pretend you're sick and stay in bed. When your father comes to see you, ask him to send Tamar to bring you food and take care of you.' 2 Samuel 13:8 - Modern Text Bible

(Jonadab comes up with a manipulative plan to get Tamar alone with Amnon.)
