Genesis 27:18-23

18So he went in to his father and said, "My father." And he said, "Here I am. Who are you, my son?"

19Jacob said to his father, "I am Esau your firstborn. I have done as you told me; now sit up and eat of my game, that your soul may bless me."

20But 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."

21Then Isaac said to Jacob, "Please come near, that I may feel you, my son, to know whether you are really my son Esau or not."

22So 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."

23And he did not recognize him, because his hands were hairy like his brother Esau's hands. So he blessed him.
