Genesis 27:14-23 ESV
So he went and took them and brought them to his mother, and his mother prepared delicious food, such as his father loved. Then Rebekah took the best garments of Esau her older son, which were with her in the house, and put them on Jacob her younger son. And the skins of the young goats she put on his hands and on the smooth part of his neck. And she put the delicious food and the bread, which she had prepared, into the hand of 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, that your soul 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, “Please come near, that I may feel you, my son, to know whether you are really my son Esau or not.” 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.
