Then Nathan went to his house, and Yahweh struck the child that the wife of Uriah bore for David, and he became ill.

And Amnon {was so frustrated that he felt ill} because of Tamar his sister, because she [was] a virgin, and it [was] too difficult in Amnon's eyes to do anything with her.

Then Jonadab said to him, "Lie down on your bed and appear ill. If your father comes to see you, you shall say to him, 'Please let Tamar my sister come and give me food to eat, and let her prepare the food before my eyes, in order that I may see it and eat from her hand.'"

So Amnon lay down and pretended to be ill, and the king came to see him. Amnon said to the king, "Please let Tamar my sister come, and let her bake two cakes before my eyes that I may eat from her hand."

After this, the LORD afflicted the child that Uriah's wife had born to David, and the child became very ill. David begged God on behalf of the youngster. He fasted, went inside, and spent the night lying on the ground.
