When Jacob is advised by his mother to deceive his father, we see the singular act of dishonor: Jacob vs his father Isaac. But if Jacob ignored his mother, he would be dishonoring her.
There’s a dilemma we are supposed to notice. How does a righteous son proceed?
I suspect it is easier for Jacob to honor his mother simply because he knew that she loved him. The text clearly states that Rebekah favored him, and that Isaac favored Esau.
Perhaps there is wisdom in this.
