Why did he request salvation from his sins?
Radak: It is the reason for his illness and pain. Atone for my sins, and save me from them!
Malbim: Physicality should not drag the Nefesh down via sins, to the point that it will not attain its eternal hope.
What is "Cherpas Naval"?
Rashi: (The boor should not shame me.) Bring plagues also on him, so he cannot say 'you are afflicted, and we are not afflicted.' This Tefilah caused illness to come on them.
Radak: The boor reviles me in his heart when he comes to visit me, and externally reviles me with his mouth, for I am pained, and he is healthy and serene.
Malbim: It is the shame of the boor, who loses his world and his end (world to come).
