Yakov acted with too much enthusiasm, with too much pleasure, when denying his brother Esav even the consideration of an opportunity to initiate change for the better. For this Yakov was punished. [Rashi 32:23]<br><br>There was a little more [or less] than altruism in the rivalry between the twins, Yakov and Esav.<br>
<br>No balanced person, and certainly neither Yakov nor Rivkah, considered for even a single moment that Yitzchak's blessings, conferred in error upon a thoroughly undeserving first-born son, could or would compel Gd to favour someone as evil as Esav.<br>
<br>Perhaps, the energy and enthusiasm in manipulating Yitzchak was also driven by this less than altruistic rivalry between the twins.<br><br>Even suggesting that concern for Yitzchak, who would be crushed upon eventually discovering that he had blessed an ugly brute, does not permit this type of deception. See Talmud Shavuos 30a -which explains, MidVar Sheker TirChak [keep well away from deception] that even for true and noble ends we may not foster misrepresentation.<br>
<br>Man's actions and thoughts are always suspect.<br><br><br>Best,<br><br>Meir G. Rabi
