Kabbalah su Genesi 3:14

For that reason Jacob behaved with cunning and guile, and brought blessings on Jacob, who resembled Adam, that were taken from the serpent of the lying lips, who talked and acted deceitfully, in order to incite and bring curses upon the world. For that reason, Jacob behaved with cunning and misled his father, so as to bring blessings upon the world and snatch from the serpent what he withheld from the world. This was measure for measure, of which it is written, "For he loved cursing, and it came to him, and he delighted not in blessings, and it was far from him" (Tehilim 109:17). About him, the verse reads, "you are cursed above all cattle, and above every beast of the field" (Beresheet 3:14). He stayed accursed forever more, and Jacob came and took the blessings from him.
