In Tol’dot we learn that Jacob, the homespun man, is wilier than his brother Esau, the skilled hunter. While Jewish commentators ascribed many negative traits and behaviors to Esau, a later portion reveals his positive ability to forgive.
Jacob and Esau had different traits even in the womb. Jacob is the brother who gains the favor of the Rabbis ultimately, but in Tol’dot, he is conniving and conspiring. Esau is viewed by the biblical author as “impetuous and brash” and by later commentators as a “wild beast.” The words in Tol’dot imply that their character was inescapable.
