Fiction Found in the Bible

One fiction story is told in the Bible. The protagonist is Nathan. The antagonist is David.

The story starts off with Nathan speaking. "There were two men in a certain town, one rich and the other poor. The rich man had a very large number of sheep and cattle, but the poor man had nothing except one little ewe lamb he had bought. He raised it, and it grew up with him and his children. It shared his food, drank from his cup and even slept in his arms. It was like a daughter to him.” (Can’t you feel the love and see the kids playing with the lamb?) 

"Now a traveler came to the rich man, but the rich man refrained from taking one of his own sheep or cattle to prepare a meal for the traveler who had come to him. Instead, he took the ewe lamb that belonged to the poor man and prepared it for the one who had come to him."
(Your feeling probably have switched to hatred for the rich man.)

David burned with anger against the man and said to Nathan, "As surely as the LORD lives, the man who did this deserves to die!  He must pay for that lamb four times over, because he did such a thing and had no pity." 

Here is where the plot changes. Nathan says to David, “YOU ARE THE MAN!”

What a revelation. Can you see the face of David dropping from anger to confusion to fear? David is busted. His secret affair and murder is revealed through a fiction story.
