'Sick' in the Bible

And Nathan departed to his house. And Jehovah smote the child that Urijah's wife bore to David, and it became very sick.

And Amnon was so vexed, that he fell sick for his sister Tamar; for she was a virgin; and it seemed difficult for Amnon to do the least thing to her.

And Jonadab said to him, Lay thee down on thy bed and feign thyself sick; and when thy father comes to see thee, say to him, I pray thee, let my sister Tamar come, and give me food, and dress the food in my sight, that I may see it, and eat it from her hand.

So Amnon lay down and feigned himself sick; and the king came to see him, and Amnon said to the king, I pray thee, let Tamar my sister come, and make a couple of cakes in my sight, that I may eat from her hand.
