Ambrose of Milan : Accordingly Jacob received his brother's clothing, because he excelled the elder in wisdom. Thus the younger brother took the clothing of the elder because he was conspicuous in the merit of his faith. Rebekah presented this clothing as a symbol of the church; she gave to the younger son the clothing of the Old Testament, the prophetic and priestly clothing, the royal Davidic clothing, the clothing of the kings Solomon and Hezekiah and Josiah. She gave it too to the Christian people, who would know how to use the garment they had received, since the Jewish people kept it without using it and did not know its proper adornments. This clothing was lying in shadow, cast off and forgotten; it was tarnished by a dark haze of impiety and could not be unfolded further in their confined hearts. The Christian people put it on, and it shone brightly. They made it bright with the splendor of their faith and the light of their holy works. Isaac recognized the familiar fragrance that attached to his people. He recognized the clothing of the Old Testament, but the voice of the people of old he did not recognize; therefore he knew that it had been changed. For even today the same clothing remains, but the confession of a people of greater devotion begins to sound harmonious; Isaac was right to say, "The voice indeed is the voice of Jacob, but the hands are the hands of Esau." And Isaac "smelled the fragrance of his garments." And perhaps that means that we are not justified by works but by faith, because the weakness of the flesh is a hindrance to works, but the brightness of faith puts the error that is in humanity's deeds in the shadow and merits for us the forgiveness of our sins. — On Jacob and the Blessed Life, Book 2, Chapter 2, Section 9 Hippolytus of Rome : The fact that Jacob wears the robe signifies that the Word has been clothed by the flesh, while the skins of the kids wrapped around his arms show that he has received in himself all our sins by stretching his hands and arms on the cross, as Isaiah himself has said: "He has borne our sins and carried our diseases." — ON THE BLESSINGS OF ISAAC AND JACOB 6 Jerome : (Verse 15) And Rebecca took the garments of her elder son Esau, which were greatly desired by him at home. And in this place, the Hebrews tradition holds that the firstborns, who had fulfilled the duties of the priests, had a priestly garment, which they wore to offer sacrifices to God before Aaron was chosen for the priesthood. — Hebrew Questions on Genesis John Chrysostom : Notice here, I ask you, along with Rebekah's affection, her great wisdom as well. Since it was mentioned previously that one was hairy and the other smooth-skinned, she clad him in Esau's clothing, the text says, and covered his skin, disguising him all over so as to bring off the deception. And after putting the food and bread into Jacob's hands she had him take it to his father.Consider here again, I ask you, how it was all due to grace from above. I mean, whereas we contribute our utmost, we enjoy in generous measure as well cooperation from God. You see, in case we show indifference and prove recalcitrant, he wants us also to make an effort so that in this way our contribution may be demonstrated. It is neither the case that everything is due to help from on high (rather we, too, must contribute something), nor on the other hand does he require everything of us, knowing as he does the extra-ordinary degree of our limitations. On the contrary, out of fidelity to his characteristic love and wishing to find some occasion for demonstrating his own generosity, he awaits the contribution of what we have to offer. — HOMILIES ON Genesis 53.6-7
