創世記 27:32 註釋：Ramban, Tur HaArokh & Tze'enah Ure'enah

WHO ART THOU? When Esau said to him, Let my father arise,²²⁷Verse 31 here. Isaac thought that it was Jacob, i.e., that because Jacob knew that he had eaten of Esau’s venison and blessed Esau, he too prepared savory meats so that he should bless him also. Therefore he asked, Who art thou?, in order to know the truth.²²⁸If Isaac did not think him to be Jacob, why should he ask, “Who art thou?” He himself had told Esau to make him savory food, and now he came and said, “Let my father arise.” However, since Ramban explains that Isaac thought him to be Jacob, the question is understandable.

מי אתה?, “Who are you?” He thought that he was addressing Yaakov who when he had heard that his father had eaten of Esau’s venison, had also prepared a dish for him in order to secure a blessing for himself. He therefore asked: “who are you?” in order to ascertain the true facts.

“Who are you? He said, I am your son, Esau, your firstborn” [27:32]. Isaac asked: who are you? He said: I am your firstborn son, Esau.
