When Isaac was old and his eyes were dim so that he could not see, he called Esau his older son, and said to him, "My son"; and he answered, "Here I am."
He said, "Behold, I am old; I do not know the day of my death.
Now then, take your weapons, your quiver and your bow, and go out to the field, and hunt game for me,
and prepare for me savory food, such as I love, and bring it to me that I may eat; that I may bless you before I die."
So Jacob went near to Isaac his father, who felt him and said, "The voice is Jacob's voice, but the hands are the hands of Esau."
And he did not recognize him, because his hands were hairy like his brother Esau's hands; so he blessed him.
