This story is a present-day twist on the biblical story of Jacob and his mother Rebecca plotting together against the elderly father Isaac, who is lying on his deathbed, in order to get their hands on the inheritance, and on the power in the family. This is no old fairy tale. Its power is here and now, in each one of us. 
Listening to Yankle telling his take on events, we understand the bitter rivalry between him and his brother. We become intimately engaged with every detail of the plot, and every shade of emotion in these flawed, yet fascinating characters. He yearns to become his father’s favorite son, seeing only one way open to him, to get that which he wants: deceit 

“What if my father would touch me,” asks Yankle. In planning his deception, it is not love for his father, nor respect for his age that drives his hesitation—rather, it is the fear to be found out. 

And so—covering his arm with the hide of a kid, pretending to be that which he is not—he is now ready for the last moment he is going to have with his father.
