וַיֹּ֗אמֶר הַגִּ֤שָׁה לִּי֙ וְאֹֽכְלָה֙ מִצֵּ֣יד בְּנִ֔י לְמַ֥עַן תְּבָֽרֶכְךָ֖ נַפְשִׁ֑י וַיַּגֶּשׁ־לוֹ֙ וַיֹּאכַ֔ל וַיָּ֧בֵא ל֦וֹ יַ֖יִן וַיֵּֽשְׁתְּ׃
以撒說：«把野味遞到我面前來，讓我吃我兒子的野味，好讓我親自為你祝福。»雅各就遞給他，他便吃了；雅各又拿酒來給他，他就喝了。
Radak
ויאמר...ואכלה מציד בני, as if he had said: “from your venison.” However, he used a formulation which was customary at the time.
Chizkuni
ויבא לו יין וישת, “he brought his father wine and Yitzchok drank it.” Wine was apt to confuse a person’s mind at times, so that he would not proceed further with worrying if this was indeed Esau or an impostor.
Tur HaArokh
ויבא לו יין וישת, “he brought him wine, and he (Yizchok) drank it.” Where did Yaakov take the wine from, seeing that his mother had only given him bread to accompany the delicacies she had prepared? According to the Midrash the angel Gavriel brought the wine whose origin was in Gan Eden to Yaakov. Presumably, the words of the Midrash were inspired by the fact that this is the only time in Scripture that the drinking of wine is described as having only positive results. When wine is mentioned as a gift by Malki Tzedek to Avraham, it was a subsidiary to the bread. (Genesis 14,18)
