Commentaire de citation sur La Genèse 27:13

ויאמר...אנכי עשו בכרך, some people wonder how Yaakov, a righteous person, could say something like this, an outright lie in their opinion. Actually, the matter is not so strange seeing that Yaakov knew that he was entitled to the blessing more than his brother, and that the spirit of prophecy would come to rest on Yitzchok so that he would bless him instead. If, in a situation such as this, the tzaddik changes words so that they sound like a lie, this is in order and does not reflect on him negatively. Our example is Samuel I 16,2 where G’d tells the prophet Samuel to go and crown one of Yishai’s sons as the future king of Israel. In order to escape suspicion in case Sha-ul would challenge his trip to Chevron where Yishai lived, G’d told him to take with him a calf and to claim that he was taking it to Chevron to offer as a sacrifice. Besides, Yaakov was well aware that both his father and his grandfather had on occasion told lies about the marital status of their wives. No one ever accused either as having told lies, seeing there was an adequate reason for telling such a lie. Yaakov therefore was entitled to tell such a lie under the circumstances, and by representing himself as the one who was to get this blessing this did not turn him into a liar. Furthermore, in doing what he did he carried out his mother’s instructions. The Torah specifically orders איש אמו ואביו תיראו “you shall be in awe of your mother and father.” (Leviticus 19,3) Also, his mother was known to be a prophetess, so that her instructions could be trusted without reservations. Onkelos translates verse 13 עלי קללתך בני, to mean that what Rivkah said was “I have received a prophetic vision telling me that you will not be cursed.”

Imre Noam also gives these explanations and gives another explanation. “Your curse be upon me.” That is to say, if your father will not want to allow you to inherit, I will give you my marriage contract. I will fulfill for you that you will have enough.⁵³Imre Noam, Genesis, 27:13.
