GEN1239 Avoid Causing a Quarrel between Parents.   If your mother tells you, “Son, please do this,” and then your father angrily exclaims, “What is that you have done? Who told you to do that?” do not reply, “It was mother who asked me to do it,” for then you would be to blame if your father became enraged at your mother and cursed her, and it is counted as if you had cursed her.  … When Jacob demurred [to Rebekah’s request], fearing that his father might realize the deception, Rebekah replied [this verse].   She meant to say, “Don’t tell your father that I ordered you to bring the delicacies, lest he become angry and curse me, which would be counted as if you had cursed me. But if he does, let any curse be on me, my son.”   (citing Sefer Chasidim, 336).   ISAACS 134
