In the final moments of her life Rachel Imeinu called her newborn son Ben Oni. In the very same passuk Yaakov calls the child Binyamin. 

Why doesn't Yaakov call Binyamin by the name Rachel chose for him? 

We know that Yaakov loved Rachel so deeply. Why do they spend their last moments on earth together fighting over the child's name?

Why does the Torah refer to Binyamin as Binyamin and not Ben Oni? Does Hashem somehow choose Yaakov's side over Rachel? Does Hashem ignore the wish of a dying Tzadeikes like Rachel?

In this shiur, Rav Burg explains how there was no argument at all between Yaakov and Rachel. Instead our Avos laid out some of the fundamental principles, indeed the blueprint, for how we parent children who are in pain.
