Upon me be thy curse, my son. Here Rebekah sins again, because she burns with such hasty zeal that she does not consider how highly God disapproves of her evil course. She presumptuously subjects herself to the curse. But whence this unheeding confidence? Being unfurnished with any divine command, she took her own counsel. Yet no one will deny that this zeal, although preposterous, proceeds from special reverence for the word of God. For since she was informed by the oracle of God, that Jacob was preferred in the sight of God, she disregarded whatever was visible in the world, and whatever the sense of nature dictated, in comparison with God's secret election. Therefore we are taught by this example, that every one should walk modestly and cautiously according to the rule of his vocation; and should not dare to proceed beyond what the Lord allows in his word.

only obey my voice, and go fetch me them; the two fat kids of the goats from the flock.

and his mother said unto him, Upon me be thy curse--His conscience being soothed by his mother, preparations were hastily made for carrying out the device; consisting, first, of a kid's flesh, which, made into a ragout, spiced with salt, onions, garlic, and lemon juice, might easily be passed off on a blind old man, with blunted senses, as game; second, of pieces of goat's skin bound on his hands and neck, its soft silken hair resembling that on the cheek of a young man; third, of the long white robe--the vestment of the first-born, which, transmitted from father to son and kept in a chest among fragrant herbs and perfumed flowers used much in the East to keep away moths--his mother provided for him.
