Now the first came forth red, all over like a hairy garment; and they named him Esau. Afterward his brother came forth with his hand holding on to Esau’s heel, so his name was called Jacob (Gen. 25:25-6)
The Torah is telling us something very important here. Esau is defined by his appearance – because others see him that way, and he ultimately also sees himself the same way.
The Torah never tells us what Jacob looks like. It only tells us what he does. Right or wrong, Jacob is a man who is the sum of his actions, of his decisions. Jacob always dedicates himself to whatever course of action he has chosen.
This, of course, is necessary to any Torah life: to be someone who is known for their choices and actions, not their mere appearance..
