In this Chapter, Jacob, with the help of his mother, secures the blessing of the birthright. Rebekah remembers the words of YeHoVaH spoken to her which caused her to do what she did.  Jacob knew what was being proposed and saw the danger in it, but his mother assumed all responsibilities even the possibility of being cursed because she was operating in what she had heard the Father say to her. 

Jacob obeyed his mother and pretended to be Esau in order to secure the blessing of the firstborn.  Jacob honestly and legally secured the birthright from Esau and here he obeys his mother to secure the blessing of the birthright from his father Isaac.
