אוּלַ֤י יְמֻשֵּׁ֙נִי֙ אָבִ֔י וְהָיִ֥יתִי בְעֵינָ֖יו כִּמְתַעְתֵּ֑עַ וְהֵבֵאתִ֥י עָלַ֛י קְלָלָ֖ה וְלֹ֥א בְרָכָֽה׃
Quizá me tentará mi padre, y me tendrá por burlador, y traeré sobre mí maldición y no bendición.
Rashi
ימשני HE WILL FEEL ME — The word is of the same root as the verb in (Deuteronomy 28:29) “One groping (ממשש) at noon-day”.
Chizkuni
והבאתי עלי קללה, “I will bring a curse upon myself as I am bound to lie by saying ‘I am Esau;’ if I do not lie, he will not believe me.” Furthermore, all he has to do is to touch me and he will know that I am not Esau. He will curse me for having deceived him.”
Ramban
PERHAPS MY FATHER WILL FEEL ME. The reason that Isaac will feel him is not for the purpose of recognition. Instead, Jacob said, “Perhaps he will bring me near him to kiss me or to put his hand on my face in the manner of a father demonstrating affection for his son, and in feeling me he will discover that I am smooth.”
Now I wonder why Jacob was not afraid of vocal recognition for all people are recognizable by their voice as our Rabbis have said, “How is a blind man permitted to live with his wife? And how are people permitted to live with their wives at nighttime? Only by vocal recognition.”206Chullin 96a. Now if ordinary people have such power of recognition, what of Isaac, who was wise and expert in distinguishing between his sons?207As Scripture testifies (25:28), his love was centered on one. He should truly have the power of recognition by voice. Perhaps the brothers had similar voices, and therefore the Sages said that the verse, The voice is the voice of Jacob,208Further, Verse 22. refers not to Jacob’s voice but to his words, i.e., that he speaks gentle language and mentions the Name of Heaven.209Bereshith Rabbah 65:16. Due to the fact that the voices of the brothers were alike, it was necessary for the Sages to interpret the verse, The voice is the voice of Jacob, as referring to the kind of language Jacob used. It may be that he altered his voice in order to speak as his brother did, for there are people who know how to do this.
