'Sick' in the Bible

Jonadab replied to him, "Lie down on your bed and pretend to be sick. When your father comes in to see you, say to him, 'Please let my sister Tamar come in so she can fix some food for me. Let her prepare the food in my sight so I can watch. Then I will eat from her hand.'"

So Amnon lay down and pretended to be sick. When the king came in to see him, Amnon said to the king, "Please let my sister Tamar come in so she can make a couple of cakes in my sight. Then I will eat from her hand."
