When it became plain to Esau that he could not induce his father to annul the blessing bestowed upon Jacob, he tried to force a blessing for himself by an underhand trick. He said: "Hast thou but one blessing, my father? bless me, even me also, O my father, else it will be said thou hast but one blessing to bestow. Suppose both Jacob and I had been righteous men, had not then thy God had two blessings, one for each?"
The Lord Himself made reply: "Silence! Jacob will bless the twelve tribes, and each blessing will be different from every other." But Isaac felt great pity for his older son, and he wanted to bless him, but the Shekinah forsook him, and he could not carry out what he purposed. Thereupon Esau began to weep.
He shed three tears--one ran from his right eye, the second from his left eye, and the third remained hanging from his eyelash. God said, "This villain cries for his very life, and should I let him depart empty-handed?" and then He bade Isaac bless his older son.
