Rashi seems to say that we know that a bor of 9 is an av by way of a diyuk from the possuk of Vehamais yiyyeh lo. What is the diyuk?

When learning Bava Kama, I did not find any Acharonim who discuss your question, so please find attached my suggestion which I copied from my own notes. A complicated issue such as this lends itself better to Lashon ha'Kodesh, so I have attached the file as is.
P.S. I would appreciate any comments or feedback you may have.
