Musar על קידושין 62:19

As to the external mechanics needed to prevent detection, Rebeccah provided the skins of these goats and put them on Jacob's hands and arms. She also had Esau's clothes that she dressed Jacob in. It is interesting that the Torah describes Rebeccah as personally garbing Jacob in those skins, that Jacob did not do so himself (27,15-16). Why did Jacob allow his mother to perform a personal service such as this for him, instead of Jacob performing a personal service for his mother, part of the commandment to honor one's mother?
