Genesis 27:1-4, 15-23
When Isaac was old and his eyes were dim so that he could not see, he called his elder son Esau and said to him, “My son”; and he answered, “Here I am.” He said, “See, 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. Then prepare for me savory food, such as I like, and bring it to me to eat, so that I may bless you before I die.”
Then Rebekah took the best garments of her elder son Esau, which were with her in the house, and put them on her younger son Jacob; and she put the skins of the kids on his hands and on the smooth part of his neck. Then she handed the savory food, and the bread that she had prepared, to her son Jacob.
So he went in to his father, and said, “My father”; and he said, “Here I am; who are you, my son?” Jacob said to his father, “I am Esau your firstborn. I have done as you told me; now sit up and eat of my game, so that you may bless me.” But Isaac said to his son, “How is it that you have found it so quickly, my son?” He answered, “Because the Lord your God granted me success.” Then Isaac said to Jacob, “Come near, that I may feel you, my son, to know whether you are really my son Esau or not.” So Jacob went up to his father Isaac, who felt him and said, “The voice is Jacob’s voice, but the hands are the hands of Esau.” He did not recognize him, because his hands were hairy like his brother Esau’s hands; so he blessed him.
