ולא...ויאמר אתה זה, this is a form of a question, even though it is not accompanied by the letter ה in front of the word אתה which we would have expected to introduce such a question. We find a similar construction in Kings I 1,24 אתה ומרת אדניה ימלוך אחרי? “did you (King David) say that “Adoniah will rule after me?” There are numerous similar constructions in Scripture. The reason why Yaakov phrased this as a question was that he was still not convinced that it was Esau because the voice [as well as the mode of speech. Ed.] was so similar to that of Yaakov. He was afraid of appearing as swindling Esau to whom he had promised the blessing, if he we were to bless Yaakov instead, although he loved Yaakov dearly. This is why he still continued with the examination.
